In pre-PBL header is stored size of code which BootROM copies from SD card
to L2/SRAM. This size has upper limit of L2 cache size. In most cases this
is size of U-Boot SPL or size of L2 cache.
Therefore this size in pre-PBL header cannot be used for determining size
of proper U-Boot.
So always use CONFIG_SYS_MMC_U_BOOT_SIZE for determining size of proper
U-Boot which stored on SD card.
mmc: fsl_esdhc_spl: pre-PBL: check for BOOT signature instead of MBR/DBR
Pre-PBL BootROMs (MPC8536E, MPC8569E, P2020, P1011, P1012, P1013, P1020,
P1021, P1022) require custom BOOT signature on sector 0 and MBR/DBR
signature is not required at all.
So add check for BOOT signature and remove check for MBR/DBR.
This allows U-Boot SPL to load proper U-Boot on pre-PBL BootROMs platforms
also from SD cards which do not have MBR/DBR signature on sector 0.
powerpc: mpc85xx: Rename _start_e500 symbol to _start
The real entry point is _start_e500. There is no _start symbol at all. So
rename _start_e500 to _start for convension that _start symbol is used as
entry point.
_start symbol contains only 32-bit data number 0x27051956 despite it is
marked as text section. This magic number is IH_MAGIC which is used for
marking uboot image header.
mpc85xx start.S code does not define valid uboot image header, so IH_MAGIC
number in _start symbol is useless there.
Moreover this _start symbol is not used at all. Entry point is at symbol
_start_e500.
So because this _start symbol is not used for anything, completely remove
it with IH_MAGIC number. After _start symbol was _start_cont symbol, so
replace all relative address calculations by _start_cont.

arm: apple: Point stdout-path to framebuffer when keyboard present
Unless you have a spare Apple Silicon machine, getting access to

the framebuffer is likely to be the most convenient output device
for most users. While U-Boot will output to both serial and

This behaviour can be overridden by setting the "stdout" variable

The documentation for CONFIG_IS_ENABLED() in include/linux/kconfig.h
implies that we will get the correct behaviour, but the actual behaviour
differs such that this condition is now always false.
This stopped TPL being able to load the device tree blob at least on the
ROCKPro64 board (RK3399 SoC), since the wrong device tree location was
chosen.
The issues causing this behaviour with CONFIG_IS_ENABLED() are:
1. The documentation implies that CONFIG_SPL_BUILD =>
CONFIG_SPL_<option> is considered before the TPL equivalent.
Actually, the TPL options have higher priority - see definition of
_CONFIG_PREFIX.
2. The documentation implies a fallthrough, eg. if CONFIG_SPL_BUILD is
defined but the CONFIG_SPL_<option> is not, then it will proceed to
check if CONFIG_TPL_BUILD
Actually, if CONFIG_TPL_BUILD is defined, then it stops there
and CONFIG_SPL_BUILD is not considered - see definition of
_CONFIG_PREFIX.
During TPL build, at least for the ROCKPro64, both CONFIG_TPL_BUILD
and CONFIG_SPL_BUILD are defined, but because of the above, only TPL
options are considered. Since there is no CONFIG_TPL_SEPARATE_BSS,
this fails.

- eliminate some redundant EEPROM reads (the EEPROM must be read in
SPL before relocation, in SPL after relocation, and in U-Boot init.
All subsequent uses can use the global structure)
- remove unnecessary header files and alphabatize includes

imx8m{m,n}-venice-gw7902: add support for GPY111 phy
The TI DP83867 phy has been replaced with the MaxLinear GPY111 phy
due to part availability. Add support for it:
- increase post-reset time to 300ms per datasheet
- add tx-delay/rx-delay config

arm: dts: imx8m*-venice: add gpio hog support
Add gpio hog support for board-specific gpio lines:
- put hogs in u-boot.dtsi so as to keep the regular dts files
in sync with the kernel. The hogs will not be put in the kernel
as that makes them un-usable by userspace as well as
re-initializes them to dt defaults overriding changes which may
have been done by bootloader commands.
- specify gpio names and initial config
- enable GPIO_HOG

board: gateworks: venice: use common GSC driver
Use the common GSC driver.
This allows us to do some additional cleanup:
- rename gsc{.c,.h} to eeprom{.c.h} for clarity
- collapse eeprom_get_dev
- remove unnecessary header files and alphabatize includes
