Errata ID i2331 CPSW: Device lockup when reading CPSW registers
Details: A device lockup can occur during the second read of any CPSW
subsystem register after any MAIN domain power on reset (POR). A MAIN
domain POR occurs using the hardware MCU_PORz signal, or via software
using CTRLMMR_RST_CTRL.SW_MAIN_POR or CTRLMMR_MCU_RST_CTRL.SW_MAIN_POR.
After these resets, the processor and internal bus structures may get
into a state which is only recoverable with full device reset using
MCU_PORz.
Due to this errata, Ethernet boot should not be used on this device.
Workaround(s): To avoid the lockup, a warm reset should be issued after
a MAIN domain POR and before any access to the CPSW registers. The warm
reset realigns internal clocks and prevents the lockup from happening.
Workaround above errata by calling do_reset() in case of cold boot in
order to trigger warm reset. This needs enabling SYSRESET driver in R5
SPL to enable TI SCI reset driver.

This converts the following to Kconfig:
CONFIG_SYS_SPL_MALLOC_SIZE
CONFIG_SYS_SPL_MALLOC_START
We introduce a default value here as well, and CONFIG_SYS_SPL_MALLOC to
control if we have a malloc pool or not.

- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
board config header files.

This converts the following to Kconfig:

Note that the da850evm platforms were violating the "only use one" rule
here, and so now hard-code their BSS limit.

This converts the following to Kconfig:

Note that we need to make TPL_MAX_SIZE be hex, and so move and convert the
existing places.

Kconfig symbols for SYS_MMC_ENV_DEV and SYS_MMC_ENV_PART have been added by
commit 7d08077334. Therefore, move the
definitions of configs to corresponding board defconfig files and enable
configs to save env in eMMC.
Also enable config for FAT write in U-Boot.

CONFIG_SPL_TEXT_BASE was set to 0x70000000 in the commit,
"26f32c32b250 configs: am64x_evm_*_defconfig: Rearrange the components in
SRAM to satisfy the limitations for USB DFU boot mode". This change seems
to have been dropped during a merge commit.
Therefore, fix this by setting CONFIG_SPL_TEXT_BASE to 0x70000000.

For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.
Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.
Given below is the placement of various data sections in SRAM
