Subject: arm: mach-k3: j721e: Move booting of Main R5FSS Core0 to A72 U-Boot
X-Git-Tag: v2025.01-rc5-pxa1908~1772^2~5
X-Git-Url: http://git.dujemihanovic.xyz/browse.php?a=commitdiff_plain;h=05e858aefe8da523b25080ad9034a9322f7a1d20;p=u-boot.git
arm: mach-k3: j721e: Move booting of Main R5FSS Core0 to A72 U-Boot
The Main R5FSS Core0 on J721E SoCs is originally booted from R5 SPL
itself to achieve certain product-level early-boot metrics. This is
no longer supported after the R5 SPL re-architecture (support merged
for v2021.10-rc1). Move the booting of this core altogether from R5
SPL to A72 U-Boot.
The env variables are left as is for now, and will be cleaned up
in a subsequent patch.
