Re: [U-Boot] [PATCH v2 1/6] spl: add Kconfig option to clear bss early

Hi,

On Sat, 16 Mar 2019 at 04:13, Simon Goldschmidt simon.k.r.goldschmidt@gmail.com wrote:

This introduces a new Kconfig option SPL_CLEAR_BSS_F. If enabled, it clears the bss before calling board_init_f() instead of clearing it before calling board_init_r().

This also ensures that variables placed in BSS can be shared between board_init_f() and board_init_r() in SPL.

Make the new option depend on ARM for now until more implementations follow.

Changes in v2:

• make CONFIG_SPL_CLEAR_BSS_F depend on ARM for now

The current restriction is that you are not allowed to use BSS before board_init_r().

Can you please add a motivation to change this?
