Total Compute is based on ARM architecture and has
the following features enabled in u-boot:
- PL011 UART
- PL180 MMC
- NOR Flash
- FIT image with Signature
- AVB
Signed-off-by: Usama Arif
---
Changes for v2:
- Added arch/arm/dts/total_compute.dts to
board/armltd/total_compute/MAINTAINERS
- Added bootm_size of 512 MB for total compute board.
Changes for v3:
- Removed fdt_high and initrd_high to allow relocation
