KASLR, or Kernel Address Space Layout Randomization, is a security
feature in the Linux kernel that randomizes the memory location
where the kernel is loaded during boot.
OP-TEE RNG is a Random Number Generator (RNG) component within the
Open Portable Trusted Execution Environment (OP-TEE) which provides
a random number to U-BOOT and U-BOOT provides this random number
as seed value to the LINUX kernel for KASLR.
Add KASLR OPTEE RNG support across K3 devices by enabling the required
configs.

Add dram support for the MT53E1G32D2FW-046 RevC part which is a single die

- use a previously unused EEPROM byte to denote a variant of the
base config to be patched
- add a dram description string
- return the board struct from eeprom_init and pass it to the
spl_dram_init function so that it has access to the EEPROM
- move ddr_init into the spl_dram_init so that it can be patched

Unlike the gate clocks which make no use of flags, most dividers in

divider_recalc_rate(). With this fix, frequency of all the clocks match
the Linux kernel's calculation.

The loop in the icicle implementation of board_fit_config_name_match()
runs strtok() to split off the vendor portion of the compatible string
using , as the delimiter. strtok() modifies a string in place, so where
the first config and compatible do not match, the compatible has been
modified by the time the loop hits the second iteration.
Since stringlists in dt land are null separated strings, the nulls
strtok() inserts to replace the delimiter increase the number of strings
in the compatible list. When the second iteration of the loop calls
fdt_stringlist_get(), it gets the vendorless portion of the first
compatible string, rather than the second compatible string. Copy each
compatible before calling strtok() to avoid this problem.
The temporary string the compatible is copied to is statically
allocated, as attempts to dynamically allocate it at this stage of boot
were met with "alloc space exhausted" errors.
