Subject: [PATCH v1] arm: socfpga: soc64: boot_scratch_cold 8 and 9 usage
documentation
From: Alif Zakuan Yuslaimi <[email protected]>
The boot_scratch_cold register is generally used for passing critical system
info between SPL, U-Boot and Linux.
Documenting the usage of boot_scratch_cold8 and boot_scratch_cold9 sticky
registers for capturing the Uncorrected Errors
(UE) and the UE Address. This is to avoid overlapping usage in the code for S10
and Agilex.
