[PATCH v4 8/8] sunxi: Move to text environment
Simon Glass
sjg at chromium.org
Fri Oct 18 01:25:31 CEST 2024
Convert these boards to use a text environment.
For the boards check, the only differences are extra spaces after the
semicolons in 'dfu_alt_info_ram' and 'partitions', both of which are
permitted.
Add in the special boot command for old kernels, dropping the
unnecessary and confusing hex prefixes.
Signed-off-by: Simon Glass <sjg at chromium.org>
---
Changes in v4:
- Drop UUID_GPT_SYSTEM and UUID_GPT_ESP definitions
- Drop special case for ARM64's devicetree subdir
- Drop unwanted quotations and indentation in KERNEL_COMPAT path
Changes in v2:
- Keep bootcmd_sunxi_compat if OLD_SUNXI_KERNEL_COMPAT is enabled
