[PATCH v2 0/3] Spacemit K3 enable Linux boot

[E Shattow <e@freeshell.de>]

Adopt some fixes needed for Linux v7.2.10+ boot and enable
BOOTSTD_FULL together with minimal env addr variable defaults.

Build and test only with vendor BSP k3-br-v1.0.10 having reduced [1]
configuration to avoid a memory resource conflict. The vendor BSP SPL
in its default configuration attempts to load opensbi separately from
u-boot main app, and also attempts to load an embedded controller OS
image, neither of which is useful for mainline opensbi, mainline
Linux, and mainline U-Boot.

Changes since v1:
- Patch 1/3 apply tags; discussion continues upstream [2] about
  whether this should be enabled in S-mode Linux or only enabled by
  M-mode firmware (e.g. U-Boot SPL and OpenSBI).
- Patch 2/3 replaced by corresponding cherry-pick from Linux v7.4-rc1
