Update the memory layout to be aligned with other platform and avoid
overlap with 32MB Linux kernel (multiv7 image).
+ Kernel => 32MiB offset = 0xC2000000
and increase the bootm size to 32MiB
+ FDT => 64MiB offset = 0xc4000000
+ SCRIPT => 65Mib offset = 0xc4100000
+ PXESCRIPT => 66Mib offset = 0xc4200000
+ SPLASHIMAGE => 67Mib offset = 0xc4300000
+ RAMDISK => 68Mib offset = 0xc4400000
(not limited size)
In sources/boot/u-boot/doc/README.distro
+ kernel_addr_r: A size of 16MB for the kernel is likely adequate.
+ pxefile_addr_r: A size of 1MB for extlinux.conf is more than adequate.
+ fdt_addr_r: A size of 1MB for the FDT/DTB seems reasonable.
+ ramdisk_addr_r: It is recommended that this location be highest in RAM
out of fdt_addr_, kernel_addr_r, and ramdisk_addr_r,
so that the RAM disk can vary in size and use any
available RAM.
+ pxefile_addr_r: A size of 1MB for extlinux.conf is more than adequate.
+ scriptaddr: A size of 1MB for extlinux.conf is more than adequate.
For suggestions on memory locations for ARM systems, you must follow
the guidelines specified in Documentation/arm/Booting
in the Linux kernel tree.
And in sources/linux-stm32mp/Documentation/arm/Booting
The zImage may also be placed in system RAM and called there. The
kernel should be placed in the first 128MiB of RAM. It is recommended
that it is loaded above 32MiB in order to avoid the need to relocate
prior to decompression, which will make the boot process slightly
faster.

ti_cm_get_macid() is used to get a syscon node from the dt, read the
efuse address and then assign the macid read from the address. Divide
these two steps into separate functions one of which can be called from
ofdata_to_platdata() while the other can be called from _probe(). This
ensures that platdata can be assigned statically in a board file when
OF_CONTROL is not enabled. Also add a macid_sel_compat in private data

When initializing DDR from R5 SPL trigger U-Boot's panic facility
rather than simply returning from the board init function as there
is little point continuing code execution. Further, as panic implies
a board reset, so using it might potentially allow to recover from
this error in certain cases such as when the init failure was caused
by a temporary glitch of some sorts.

Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
Certain parts of msmc sram can be used by DMSC or can be
marked as L3 cache. Since the available size can vary, changing
DT every time the size varies might be painful. So, query this
information using TISCI cmd and fixup the DT for kernel.
Fixing up DT does the following:
- Create a sram node if not available
- update the reg property with available size
- update ranges property
- loop through available sub nodes and delete it if:
- mentioned size is out if available range
- subnode represents l3 cache or dmsc usage.

DMSC can use certain amount of msmc memory available in the
system. Also certain part of msmc memory can be marked as L3
cache using board config. But users might not know what size
is being used and the remaining available msmc memory. In order
to fix this TISCI protocol provides a messages that can query
the available msmc memory in the system. Add support for this
message.

In order to fully support SPL_OF_CONTROL, we need BSS to be a bit
larger. This patch relocates BSS to SDRAM instead of SRAM which
is similar to how ARMv7 boards (like OMAP2+) do it.
This means two new variables are required:
CONFIG_SPL_BSS_START_ADDR set to DAVINCI_DDR_EMIF_DATA_BASE
CONFIG_SPL_BSS_MAX_SIZE is set to 0x1080000 which is 1 byte
before the location where U-Boot will load.

When booting using an SPL on am335x, if we want to support booting with
the boot ROM loader via USB (which uses RNDIS, making bootp and tftp
calls) we need to enable gadget eth in the SPL to load the main U-Boot
image. To enable CONFIG_SPL_ETH_SUPPORT, we must enable
CONFIG_SPL_ENV_SUPPORT as the environment is used by the eth support, but
we don't actually need to have environment variables saved in the SPL
environment. We do however have environment variables saved in the main
U-Boot image and enable CONFIG_ENV_OFFSET_REDUND (we are storing in raw
NAND). In such instances, even with the build config enabling both
CONFIG_CMD_SAVEENV and CONFIG_CMD_NAND, these options aren't set when
building the SPL, but CONFIG_ENV_OFFSET_REDUND still is.
Don't check this configuration option for SPL builds to enable the above
configuration.
