Setting GPIO by reading the value of the GPRT register, toggling the
correct bit and then writing it causes input values to transfer to the
output. Here's how (example):
1) set gpio 17 and 18 as input.
2) set gpio 17 output value to 0 (read gprt, change 17 to 0, write).
3) set gpio 18 output value to 0 (read gprt, change 18 to 0, write).
The problem here is that because we set 17 as input, and it's a pull-up,
when we read gprt in step 3, the bit 17 will be 1 and not 0.
Instead of doing read/write/modify, the solution is to keep track
internally of the user set GPIOs, and replace the read step with this
static variable.

strlen only reports length of string not including terminating 0 byte

Fastboot currently supports MMC and NAND flash devices. Similarly,
extend the support to SPI flash memories.
Note that in this initial implementation, partitions on the device are
not supported yet, but raw partitions can be set in U-Boot environment.
To define a raw partition descriptor, add an environment variable
similar to the MMC case:
```
fastboot_raw_partition_<raw partition name>=<offset> <size>
```
for example:
```
fastboot_raw_partition_boot=0x0 0x1000000
```

As the size of 64b ARM kernels, DTs, vendor firmware, and initial ram
disks continues to grow, the 256MB size limit set aside for image
processing by the bootm command has become too small for some K3
reference boards.
For ARMv7 removing this limit could introduce issues so move the
bootm_size variable to ti_armv7_keystone2.env and remove the limit for
any board using a TI K3 SoC.

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.

Update the ddr phy config values to those created by the mscale_v3.10
tool. The original values were obtained using mscale_v3.10. The v3.10

- add a dram description string
