Due to some hardware guy's awful work, this version is not compatible
with v3.6: the logic of BIT(0) of the reset logic is inverted! (and
v3.6.10 is horribly wrong in multiple ways), but this is what we have
to solve now.
The v3.6 expects 0x0000 set to the register for reset de-assertion,
while v3.6 does 0x0001.
This commit (ab)uses another bug of v3.6.10 to work around the issue.
The UniPhier System Bus is a 16-bit bus, which this support card is
connected to. A 32-bit write to the bus (writel() function call) is
divided into two 16-bit write transactions, with LSB the first. What
is amazing for v3.6.10 is that access to address 4N + 2 goes to 4N
(Jesus Christ!).
For clarification, things are like this:
writel(0x00010000, MICRO_SUPPORT_CARD_RESET);
is done with two bus transactions as follows
[1] write 0x0000 to address MICRO_SUPPORT_CARD
[2] write 0x0001 to address MICRO_SUPPORT_CARD + 2
For v3.6, [1] is written to the register and [2] is correctly ignored
because there is nothing at the address MICRO_SUPPORT_CARD + 2. This
is what we expect.
For v3.6.10, [1] is written to the reset register and then [2] is
over-written to the same register due to the bus access bug.
For the latter, it produces a glitch signal to the BIT[0], so the
device state is lost due to the reset pulse. This solution only
works for the start-up code.

Sometimes it is useful to jump into U-Boot directly from coreboot or UEFI
without any 16-bit init. This can help during development by allowing U-Boot
to avoid doing all the init required by the platform.
U-Boot expects its GDT to be set up correctly by its 16-bit code. If
coreboot doesn't do this (because it hasn't run the payload setup code yet)
then this won't happen.
In this case we cannot rely on the GDT settings. U-Boot will hang or crash
if these are wrong. Provide a development-only option to set up the GDT
correctly. This is just a hack so you can jump to U-Boot from any stage of
coreboot, not just at the end.

Add a driver which sets up the pin configuration on x86 devices with an ICH6
(or later) Platform Controller Hub.
The driver is not in the pinctrl uclass due to some oddities of the way x86
devices work:
- The GPIO controller is not present in I/O space until it is set up
- This is done by writing a register in the PCH
- The PCH has a driver which itself uses PCI, another driver
- The pinctrl uclass requires that a pinctrl device be available before any
other device can be probed
It would be possible to work around the limitations by:
- Hard-coding the GPIO address rather than reading it from the PCH
- Using special x86 PCI access to set the GPIO address in the PCH
However it is not clear that this is better, since the pin configuration
driver does not actually provide normal pin configuration services - it
simply sets up all the pins statically when probed. While this remains the
case, it seems better to use a syscon uclass instead. This can be probed
whenever it is needed, without any limitations.
Also add an 'invert' property to support inverting the input.

The idea to generate our pages tables from an array of memory ranges
is very sound. However, instead of hard coding the code to create up
to 2 levels of 64k granule page tables, we really should just create
normal 4k page tables that allow us to set caching attributes on 2M
or 4k level later on.
So this patch moves the full_va mapping code to 4k page size and
makes it fully flexible to dynamically create as many levels as
necessary for a map (including dynamic 1G/2M pages). It also adds
support to dynamically split a large map into smaller ones when
some code wants to set dcache attributes.
With all this in place, there is very little reason to create your
own page tables in board specific files.

information from an I2C EEPROM.
The EV3 itself initally boots from write-protected EEPROM, so no
u-boot SPL is needed.

Enable support for PMMC the TI power processor on K2G. This processor
manages all power management related activities on the SoC and and
allows the Operating Systems on compute processors such as ARM, DSP to
offload the power logic away into the power processor. U-boot just has a
load responsibility, hence the view of the hardware from a bootloader
perspective is different from the view of hardware from a Operating
System perspective. While bootloader just loads up the firmware,
Operating Systems look at the resultant system as "hardware".

Current AM57xx evm supports both BeagleBoard-X15
(http://beagleboard.org/x15) and AM57xx EVM
(http://www.ti.com/tool/tmdxevm5728).
The AM572x EValuation Module(EVM) provides an affordable platform to
quickly start evaluation of Sitara. ARM Cortex-A15 AM57x Processors
(AM5728, AM5726, AM5718, AM5716) and accelerate development for HMI,
machine vision, networking, medical imaging and many other industrial
applications. This EVM is based on the same BeagleBoard-X15 Chassis
and adds mPCIe, mSATA, LCD, touchscreen, Camera, push button and TI's
wlink8 offering.
Since the EEPROM contents are compatible between the BeagleBoard-X15 and
the AM57xx-evm, we add support for the detection logic to enable
support for various user programmable scripting capability.
NOTE: U-boot configuration is currently a superset of AM57xx evm and
BeagleBoard-X15 and no additional configuration tweaking is needed.
This change also sets up the stage for future support of TI AM57xx EVMs
to the same base bootloader build.

Many TI EVMs have capability to store relevant board information

variations can occur as part of revision changes in the platform.
In-order to support these at runtime, we for a board detection hook

so.
NOTE: All TI EVMs are capable of detecting board information based on
early clocks that are configured. However, in case of additional needs

Several TI EVMs have EEPROM that can contain board description information
such as revision, DDR definition, serial number, etc. In just about all
cases, these EEPROM are on the I2C bus and provides us the opportunity
to centralize the generic operations involved.
The on-board EEPROM on the BeagleBone Black, BeagleBone, AM335x EVM,
AM43x GP EVM, AM57xx-evm, BeagleBoard-X15 share the same format.
However, DRA-7* EVMs, OMAP4SDP use a modified format.
We hence introduce logic which is generic between these platforms
without enforcing any specific format. This allows the boards to use the
relevant format for operations that they might choose.
This module will compile for all TI SoC based boards when
CONFIG_TI_I2C_BOARD_DETECT is enabled to have optimal build times for
platforms that require this support.
It is important to note that this logic is fundamental to the board
configuration process such as DDR configuration which is needed in
SPL, hence cannot be part of the standard u-boot driver model (which
is available later in the process). Hence, to aid efficiency, the
eeprom contents are copied over to SRAM scratchpad memory area at the
first invocation to retrieve data.
To prevent churn with cases such as DRA7, where eeprom format maybe
incompatible, we introduce a generic common format in eeprom which
is made available over accessor functions for usage.
Special handling for BBG1 EEPROM had to be introduced thanks to the
weird eeprom rev contents used.
The follow on patches introduce the use of this library for AM335x,
AM437x, and AM57xx.

Early clock initialization is currently done in two stages for OMAP4/5
SoCs. The first stage is the initialization of console clocks and
then we initialize basic clocks for functionality necessary for SoC
initialization and basic board functionality.
By splitting up prcm_init and centralizing this clock initialization,
we setup the code for follow on patches that can do board specific
initialization such as board detection which will depend on these
basic clocks.
As part of this change, since the early clock initialization
is centralized, we no longer need to expose the console clock
initialization.
NOTE: we change the sequence slightly by initializing console clocks
timer after the io settings are complete, but this is not expected
to have any functioanlity impact since we setup the basic IO drive
strength initialization as part of do_io_settings.

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.
Move these options to Kconfig and tidy up board configuration:
CONFIG_FIT
CONFIG_OF_BOARD_SETUP
CONFIG_OF_SYSTEM_SETUP
CONFIG_FIT_SIGNATURE
CONFIG_FIT_BEST_MATCH
CONFIG_FIT_VERBOSE
CONFIG_OF_STDOUT_VIA_ALIAS
CONFIG_RSA
Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.
Note: Masahiro's moveconfig.py script is amazing.
