6ca43a58db env: ti: boot: Show boot status information
Add tracing printings to Linux/Android boot commands, so that we can see
what's going on. Helps to trace possible bugs on early stages and
improves the output for user (which is especially useful, because we
have a bunch of boot commands executing one by one).

a0b0ff0ae6 arm: dra7xx: Fix Linux boot from eMMC
Right now on OMAP5-based boards we have only one partition defined for
Linux boot, which is rootfs. That doesn't work with bootpart=1:2 (that
is defined in include/environment/ti/boot.h). To fix Linux boot we may
either:

 1. Change bootpart to be 1:1
 2. Or add preceding partition, so that rootfs is actually 1:2

Second choice seems more reasonable, as DFU is already using similar
partition table and can rely on bootpart to be 1:2.

This patch adds "bootloader" partition. So now eMMC layout for Linux
boot looks like this:

offset               content                 size          partition
(KiB)                                        (KiB)

This patch adapts stm32h743 disco and eval dts files to match
with U-boot requirements or add features wich are not yet
upstreamed on kernel side :

_ Add RCC clock driver node and update all clocks phandle
  accordingly.

  By default, on kernel side, all clocks was temporarly
  configured as a phandle to timer_clk waiting for a RCC
  clock driver to be available.
  On U-boot side, we now have a dedicated RCC clock driver, we
  can configured all clocks as phandle to this driver.

  All this binding update will be available soon in a kernel tag,
  as all the bindings have been acked by Rob Herring [1].

  [1] http://lkml.iu.edu/hypermail/linux/kernel/1704.0/00935.html

_ Align STM32H7 serial compatible string with the one which will be
  available in next kernel tag. The bindings has been acked by
  Rob Herring [2].
  This compatible string will be usefull to add stm32h7 specific
  feature for this serial driver.

  [2] https://lkml.org/lkml/2017/7/17/739

_ Add gpio compatible and aliases for stm32h743

_ Add FMC sdram node with associated new bindings value to
  manage second bank (ie bank 1).

_ Add missing HSI and CSI oscillators nodes needed
  by STM32H7 RCC clock driver.

  Clock sources could be:
	_ HSE (High Speed External)
	_ HSI (High Speed Internal)
	_ CSI (Low Power Internal)

  These clocks can be used as clocksource in some configuration.
  By default, HSE is selected as clock source.

_ Set HSE to 25Mhz for stm32h743i-disco and eval board

  By default, the external oscillator frequency is defined at
  25 Mhz in SoC stm32h743.dtsi file.
  It has been set at 125 Mhz in kernel DT temporarly waiting for
  RCC clock driver becomes available.

  As in U-boot we got a RCC clock driver, the real value of HSE
  clock can be used.

_ Add "u-boot,dm-pre-reloc" for rcc, fmc, fixed-clock, pinctrl,
  pwrcfg and gpio nodes.

The hummingboard2 is slightly different to the cubox i and to the
hummingboard. The GPIO pin info to probe came from solidruns
for of u-boot on github.

I have tested on a hummingboard-edge witha  imx6 solo and 512mb of

1) use fputs() to reduce cache flushes from once-per-char to
   once-per-string
2) handle \r, \t, and \b in addition to just \n for tracking
   cursor position
3) cursor row/col are zero based, not one based

9975fe96b6 efi_loader: add bootmgr
Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot.  This is added as a sub-command of bootefi.

The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi.  (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)

ad644e7c18 efi_loader: efi variable support
Add EFI variable support, mapping to u-boot environment variables.
Variables are pretty important for setting up boot order, among other
things.  If the board supports saveenv, then it will be called in
ExitBootServices() to persist variables set by the efi payload.  (For
example, fallback.efi configuring BootOrder and BootXXXX load-option
variables.)

Variables are *not* currently exposed at runtime, post ExitBootServices.
On boards without a dedicated device for storage, which the loaded OS
is not trying to also use, this is rather tricky.  One idea, at least
for boards that can persist RAM across reboot, is to keep a "journal"
of modified variables in RAM, and then turn halt into a reboot into
u-boot, plus store variables, plus halt.  Whatever the solution, it
likely involves some per-board support.

Mapping between EFI variables and u-boot variables:

  efi_$guid_$varname = {attributes}(type)value

For example:

  efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_OsIndicationsSupported=
     "{ro,boot,run}(blob)0000000000000000"
  efi_8be4df61-93ca-11d2-aa0d-00e098032b8c_BootOrder=
     "(blob)00010000"

The attributes are a comma separated list of these possible
attributes:

  + ro   - read-only
  + boot - boot-services access
  + run  - runtime access

NOTE: with current implementation, no variables are available after
ExitBootServices, and all are persisted (if possible).

If not specified, the attributes default to "{boot}".

The required type is one of:

  + utf8 - raw utf8 string
  + blob - arbitrary length hex string

95c5553ea2 efi_loader: refactor boot device and loaded_image handling
Get rid of the hacky fake boot-device and duplicate device-path
constructing (which needs to match what efi_disk and efi_net do).
Instead convert over to use efi_device_path helpers to construct
device-paths, and use that to look up the actual boot device.

Also, extract out a helper to plug things in properly to the
loaded_image.  In a following patch we'll want to re-use this in
efi_load_image() to handle the case of loading an image from a
file_path.

adae4313cd efi_loader: flesh out device-path to text
It needs to handle more device-path node types, and also multiple levels
of path hierarchy.  To simplify this, initially construct utf8 string to
a temporary buffer, and then allocate the real utf16 buffer that is
returned.  This should be mostly for debugging or at least not critical-
path so an extra copy won't hurt, and is saner than the alternative.

Helpers to construct device-paths from devices, partitions, files, and
for parsing and manipulating device-paths.

For non-legacy devices, this will use u-boot's device-model to construct
device-paths which include bus hierarchy to construct device-paths.  For
legacy devices we still fake it, but slightly more convincingly.
