110d06b2e3 arm64: zynqmp: Add SMMU support for SATA IP
AXI master interface in CEVA AHCI controller requires two unique
Write/Read ID tags per port. This is because, ahci controller uses
different AXI ID[3:0] bits for identifying non-data transfers(like
reading descriptors, updating PRD tables, etc) and data transfers
(like sending/receiving FIS).To make SMMU work with SATA we need to
add correct SMMU stream id for SATA. SMMU stream id for SATA is
determined based on the AXI ID[1:0] as shown below

	SATA SMMU ID =  <TBU number>, 0011, 00, 00, AXI ID[1:0]
	Note: SATA in  ZynqMp uses TBU1 so TBU number = 0x1, so
	      SMMU ID = 001, 0011, 00, 00, AXI ID[1:0]

Since we have four different AXI ID[3:0] (2 for port0 & 2 for port1
as said above) we get four different SMMU stream id's combinations
for SATA. These AXI ID can be configured using PAXIC register.
In this patch we assumed the below AXI ID values

 Read ID/ Write ID for Non-Data Port0 transfers = 0
 Read ID/ Write ID for Data Port0 transfers = 1
 Read ID/ Write ID for Non-Data Port1 transfers = 2
 Read ID/ Write ID for Data Port1 transfers = 3

Based on the above values,SMMU stream ID's for SATA will be 0x4c0 &
0x4c1 for PORT0, 0x4c2 & 0x4c3 for PORT1. These values needed to be
added to iommus dts property. This patch does the same.

6db82e0956 arm64: zynqmp: Fix broken architected timer interrupt trigger
Extract from Linux mainline patch:
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

f07d76c00d rockchip: fix turning off boot-mode via Kconfig
The ROCKCHIP_BOOT_MODE_REG option defaults to a hex value, so 0 will
show as 0x0 if a default is provided and changed via Kconfig.
However, it still will show as 0, if no default is given.

Consequently, the "is set to something other than 0" test in a
Makefile is cumbersome.  Instead this check can easily be performed in
the C-code.

This removes the ifeq-check from mach-rockchip/Makefile, adds a
matching #if-check to boot_mode.c and fixes resulting link issues (if
boot_mode.o was not included due to the Makefile check) by defining a
stub function (in case the functionality is not built in) for
setup_boot_mode in boot_mode.c.

image (SPL for the RK3188) in two steps: first 1KB to offset 0x800
in the SRAM and then the remainder to offset 0xc00 in the SRAM.
It always enters at 0x804, though.

With this changeset, the RK3188 boot removes the TPL (stub) stage and
builds a single SPL binary that utilizes the early back-to-bootrom via
the boot0-hook.

Consequently, the passing of the saved boot params via pmu->os_reg[2]
is also removed.

ecfd71891a rockchip: back-to-bootrom: replace assembly-implementation with C-code
The back-to-bootrom implementation for Rockchip has always relied on
the stack-pointer being valid on entry, so there was little reason to
have this as an assembly implementation.

This provides a new C-only implementation of save_boot_params and
back_to_bootrom (relying on setjmp/longjmp) and removes the older
assembly-only implementation.

b4806d6f1f arm: provide a PCS-compliant setjmp implementation
The previous setjmp-implementation (as a static inline function that
contained an 'asm volatile' sequence) was extremely fragile: (some
versions of) GCC optimised the set of registers.  One critical example
was the removal of 'r9' from the clobber list, if -ffixed-reg9 was
supplied.

To increase robustness and ensure PCS-compliant behaviour, the setjmp
and longjmp implementation are now in assembly and closely match what
one would expect to find in a libc implementation.

ff143d5556 arm: mark save_boot_params_ret as a function
As no '.type' was set for save_boot_params_ret in start.S, binutils
did not track whether it was emitted as A32 or T32.  By properly
marking save_boot_params_ret as a potential function entry, we can
make sure that the compiler will insert the appropriate instructions
for branching to save_boot_params_ret both for call-sites emitted as
A32 and T32.

7776cc011d arm: make save_boot_params_ret prototype visible for AArch64
The save_boot_params_ret() prototype (for those of us, that have a
valid SP on entry and can implement save_boot_params() in C), was
previously only defined for !defined(CONFIG_ARM64).

This moves the declaration to a common block to ensure the prototype
is available to everyone that might need it.

b377d22264 rockchip: boot0 hook: support early return for RK3188/RK3066-style BROM
Some Rockchip BROM versions (e.g. the RK3188 and RK3066) first read 1KB data
from NAND into SRAM and executes it. Then, following a return to bootrom, the
BROM loads additional code to SRAM (not overwriting the first block read) and
reenters at the same address as the first time.

To support booting either a TPL (on the RK3066) or SPL (on the RK3188) using
this model of having to count entries, this commit adds code to the boot0
hook to track the number of entries and handle them accordingly.

14ad6eb264 rockchip: enable boot0-hook for all Rockchip SoCs
Rockchip SoCs bootrom design is like this:
- First 2KB or 4KB internal memory is for bootrom stack and heap;
- Then the first 4-byte suppose to be a TAG like 'RK33';
- The the following memory address end with '0004' is the first
  instruction load and running by bootrom;

Let's use the boot0 hook to reserve the first 4-byte tag for all
the Rockchip SoCs.

ef70a42f0f arm: boot0 hook: move boot0 hook before '_start'
The boot0 hook on ARM does not insert its payload before the vector
table. This is both a mismatch with thec comment above it and
contradict usage of the boot0 hook on ARM64.

To fix this (and unify the semantics for ARM and ARM64), we change the
boot0-hook semantics on ARM to match those on ARM64:
  (1) if a boot0-hook is present it is inserted at the start of
      the image
  (2) if a boot0-hook is present, emitting the ARM vector table
      (and the _start) symbol are suppressed in vectors.S and
      the boot0-hook has full control over where and when it
      wants to emit these

d6a0c78a4e pylibfdt: compile pylibfdt only when dtoc/binman is necessary
Currently, pylibfdt is always compiled if swig is installed on your
machine.  It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.

"checkbinman" and "checkdtoc" are wrong.  It is odd that the final
build stage checks if we have built necessary tools.  If your platform
depends on dtoc/binman, you must be able to build pylibfdt.  If swig
is not installed, it should fail immediately.

I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
property select:ed by platforms that need them.  Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

The root cause for the failure is the eSDHC-A001 erratum:

Even though eSDHC-A001 is not documented on the i.MX51 errata document,
I have confirmed with the NXP design team that this erratum does affect
i.MX51, so fix the problem by selecting SYS_FSL_ERRATUM_ESDHC_A001

The i.MX51 ts4800 board already selects this option, but it is better

, which prevents any usage of the SD card.

The root cause for the failure is the eSDHC-A001 erratum:

"eSDHC-A001 : Data timeout counter (SYSCTL[DTOCV]) is not reliable for
values of 0x4,0x8, and 0xC" that is listed
on some PowerArchitecture chips:
https://www.nxp.com/files-static/32bit/doc/errata/MPC8379ECE.pdf

Even though eSDHC-A001 is not documented on the i.MX25 errata document,
I have confirmed with the NXP design team that this erratum does affect
i.MX25, so fix the problem by selecting SYS_FSL_ERRATUM_ESDHC_A001
at SoC level.

Successfully tested with a high speed SD card on a mx25pdk board.

07df697e14 mx25: Move MX25 selection to Kconfig
The motivation for moving MX25 selection to Kconfig is to be
able to better handle MX25 specific errata, so that an errata option
can be selected at SoC level instead of board level.

This selection method also aligns with the way other i.MX SoCs are
selected in U-Boot.

4a5a7fcac2 x86: braswell: Fix unexpected crash during Linux kernel boot
It was observed that when booting Linux kernel on Intel Cherry Hill
board, unexpected crash happens quite randomly. Sometimes kernel
just oops, while sometimes kernel throws MCE errors and hangs:

  mce: [Hardware Error]: Machine check events logged
  mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 4: c400000000010151
  mce: [Hardware Error]: TSC 0 ADDR 130f3f2c0
  mce: [Hardware Error]: PROCESSOR 0:406c3 TIME 1508160686 SOCKET 0 APIC 0 microcode 363

This looks like a hardware error per mcelog. After debugging, it
seems turning off turbo mode on the processor does not expose this
behavior, although U-Boot runs OK with turbo mode on. Suspect it is
related to an errata of Braswell processor.

To fix this, remove the Braswell cpu driver which does the turbo
mode configuration, and switch to use the generic cpu-x86 driver.
Also there is a configuration option in the FSP that turns on the
turbo mode and that has been turned off too.

febdfaabc7 x86: baytrail: Fix unstable ACPI S3 resume
It was observed that when booting a Ubuntu 16.04 kernel, doing ACPI
S3 suspend/resume sometimes causes the Ubuntu kernel hang forever.
The issue is however not reproduced with a kernel built from i386/
x86_64 defconfig configuration.

The unstability is actually caused by unexpected interrupts being
generated during the S3 resume. For some unknown reason, FSP (gold4)
for BayTrail configures the GPIO DFX5 PAD to enable level interrupt
(bit 24 and 25). As this pin keeps generating interrupts during an
S3 resume, and there is no IRQ requester in the kernel to handle it,
the kernel seems to hang and does not continue resuming.

Clear the mysterious interrupt bits for this pin.

Upstream Linux has received a few device tree updates to the RPi

This patch bumps the dts files to their 4.14 Linux counterparts
with the exception of sdhost on 32bit RPi versions. There we stay
with iproc as the sdhost driver is missing in U-Boot.

710d0cd79e armv8: fsl-layerscape: Allocate Secure memory from first ddr region
This change is required due to trusted OS (OP-TEE) not being position
independent code, it requires compile time fixed base address.

To take care of this it is assumed that all layerscape armv8 platforms
has minimum 2G ddr in first region. So we can have fixed address
space (66 MB -> (2MB for PPA + 64MB for trusted OS)) allocated from
top of first 2G ddr region and compile trusted OS with this fixed
base address.

But one exception here is ls1012 where we have only 1G (rdb) or 512M
(frdm) ddr memory. For those we can have different fixed compile time
base addresses for trusted OS.

32f1182926 ARM: Add a new arch + board for QEMU's 'virt' machine
This board builds an U-Boot binary that is bootable with QEMU's 'virt'
machine on ARM. The minimal QEMU command line is:

    qemu-system-arm -machine virt,highmem=off -bios u-boot.bin

(Note that the 'highmem=off' parameter to the 'virt' machine is required for
PCI to work in U-Boot.) This command line enables the following:
    - u-boot.bin loaded and executing in the emulated flash at address 0x0
    - A generated device tree blob placed at the start of RAM
    - A freely configurable amount of RAM, described by the DTB
    - A PL011 serial port, discoverable via the DTB
    - An ARMv7 architected timer
    - PSCI for rebooting the system
    - A generic ECAM-based PCI host controller, discoverable via the DTB

Additionally, QEMU allows plugging a bunch of useful peripherals to the PCI bus.
The following ones are supported by both U-Boot and Linux:

- To add a Serial ATA disk via an Intel ICH9 AHCI controller, pass e.g.:
    -drive if=none,file=disk.img,id=mydisk -device ich9-ahci,id=ahci -device ide-drive,drive=mydisk,bus=ahci.0
- To add an Intel E1000 network adapter, pass e.g.:
    -net nic,model=e1000 -net user
- To add an EHCI-compliant USB host controller, pass e.g.:
    -device usb-ehci,id=ehci
- To add a NVMe disk, pass e.g.:

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

// <smpl>

b44b30260f printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*().  U-Boot does not support them in a clean
way.  So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.

We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround.  Hence this
patch, to find the best home for all printk variants.  If you want to
use printk() and friends, please include <linux/printk.h>.  This header
is self-contained, and pulls in only a few headers.

When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards.  This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.

To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel".  (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.

The difference is the loglevel is build-time determined.  To save the
image size, lower priority pr_*() are compiled out.  I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.

I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

The (Qseven) BIOS_DISABLE signal on the RK3399-Q7 (Puma) keeps the
eMMC and SPI in reset initially and we need to write a GPIO to turn
them on before continuing the boot-up.

This adds the DTS entries for the additional regulator and makes
pinctrl and gpio3 available during SPL.  It also adds a hook to the
spl_board_init() to ensure that the regulator gets probed and enabled.

80e9f88e67 rockchip: spl: support a 'same-as-spl'-specifier in the spl-boot-order
It is often desirable to configure the spl-boot-order (i.e. the order
that SPL probes devices to find the FIT image containing a full U-Boot)
such that it contains 'the same device the SPL stage was booted from'
early on.  To support this, we introduce the 'same-as-spl' specifier
for the spl-boot-order property.

This commit adds:
 - documentation for the new board_spl_was_booted_from() function that
   individual SoCs/boards should provide, if they can determine where
   the SPL was booted from
 - implements the new board_spl_was_booted_from() stub function
 - adds support for handling the 'same-as-spl' specifier and calling
   into the per-SoC/per-board support code.

This also updates the documentation for the 'u-boot,spl-boot-order'
property.
