between the time the SoC sends its last command and when the NAND flash

falsely assume the flash is ready when in reality it just hasn't had enough

ti_armv7_common: env: Use args_mmc in FIT loading path
The env command 'args_fit' does not define a root path, this forces us to
embed the rootfs into the FIT image. FIT images do not need to contain a
rootfs, when they do not the kernel will fall-back to the kernel argument
'root', if this is not defined the kernel will not boot. It is safe to
add this as when we do have the rootfs in FIT this argument is ignored.
As 'loadfit' is only called from the MMC boot path, use 'args_mmc' to
correctly populate 'bootargs'.

Apparent conflict between CONFIG_BLK and CONFIG_API
Good evening,
I am trying to port FreeBSD to the ASUS Tinker Board, a computer based
on the Rockchip 3288 SoC. FreeBSD's boot loader (named loader(8)) needs
CONFIG_API to be enabled, but trying to build an U-Boot from trunk with
both CONFIG_API and CONFIG_BLK (as required for Rockchip SoC's?) leads
to the following build failure:
$ CROSS_COMPILE=arm-none-eabi- gmake tinker-rk3288_defconfig all

board: ti: am57xx: enable input on mmc clock
As per the latest pinmux data available for AM572x EVM,
rev A3, input should be enabled on MMC clock lines for
MMC2/2/3 for stable operation.
Further, AM572x TRM, SPRUHZ6, Revised June 2016, in
section 18.4.6.1.1 "Pad Configuration Registers" states
that input should be enabled for MMC 2/3/4 clock lines.
Enable input on MMC1 and MMC3 clock to match the latest
pinmux data. Input is already enabled on MMC2 clock for
BeagleBoard x15. Further, input is already enabled on all
MMCx clocks for other AM57xx boards (AM572x and AM571x
IDK).
Tested with HS and UHS SD card on AM572x EVM Rev A3.

ARM: keystone: Pass SPI MTD partition table via kernel command line
SPI U-Boot image for K2 boards have now exceeded 512K partition
allocated to it and no longer fit the partitions defined in kernel DTS
file. Therefore, pass an updated MTD partition table from U-Boot as
kernel command line arguments to avoid kernel from accidentally
modifying boot loader image that has overflowed to next user partition.
To do is, introduce a common environment file for declaring SPI
partition so that each individual boards need not repeat the same.
Choose appropriate SPI bus from board config file and pass it as command
line argument to kernel.

ARMv8: add GOT sections to the list of sections copied
Recent Linux distributions (e.g. Debian 9) include cross-compilers for
AArch64, but only for the aarch64-linux-gnu triplet only. It can thus
be expected that users will attempt to use the system cross-compiler
(instead of an aarch64-elf variant) to compile U-Boot for their ARMv8
target systems.
One key differences between an aarch64-linux-gnu and an aarch64-elf
compiler are the default settings regarding position-independent: with
the aarch64-linux-gnu compiler, the default will create and use the
global offset table.
This change-set adjusts the list of sections copied on ARMv8 to include
the GOT sections. With this added, the list matches the previous setup
for AArch32 closely.
Note that this is not an 'academic' issue, but was in fact encountered
by our QA during testing of the RK3399-Q7 BSP and resulted in an
early failure of the SPL stage during FDT setup.

env_mmc: Allow SPL to use any MMC device to load/save the environment
SPL has been restricted to use only dev 0 based on the assumption that only
one MMC device is registered. This is not always the case and many
platforms now register several devices as expected by the spl mmc boot code
For those platform SPL_ENV_SUPPORT is broken if dev is forced to 0.
A word of warning: this commit may break SPL_ENV_SUPPORT on platforms that
do not register the same MMC controllers in SPL and in u-boot (mostly iMX6
based platforms). Fortunately none of those activate SPL_ENV_SUPPORT in
their default configuration.
