3b074fb22b board: ti: ks2_evm: Over ride spl_get_load_buffer function
Currently k2 spi boot is broken as the image header
is getting copied to an invalid memory location

CONFIG_SYS_TEXT_BASE - sizeof (struct image_size)
which maps to 0xc000000 - 0x40 = 0xbffffc0 being a reserved
location.

We cannot change the CONFIG_SYS_TEXT_BASE address as the single
stage boots like UART boot will need the address to be 0xc000000
hence override the spl_get_load_buffer to have image_header
address as CONFIG_SYS_TEXT_BASE aka 0xc000000

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

5f48da9a98 ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot
For K2G, runtime DTB selection utilizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.

8efc243741 ARM: keystone2: use detected ddr3a size
Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.

This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.

For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h

e895a4b06f fdt: Allow ft_board_setup() to report failure
This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

89f44bb0ce keystone2: ecc: add ddr3 error detection and correction support
This patch adds the DDR3 ECC support to enable ECC in the DDR3
EMIF controller for Keystone II devices.

By default, ECC will only be enabled if RMW is supported in the
DDR EMIF controller. The entire DDR memory will be scrubbed to
zero using an EDMA channel after ECC is enabled and before
u-boot is re-located to DDR memory.

An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to
check the ECC error handling in kernel.
