spl: add support to booting with OP-TEE OP-TEE is an open source trusted OS, in armv7, its loading and running are like this: loading: - SPL load both OP-TEE and U-Boot running: - SPL run into OP-TEE in secure mode; - OP-TEE run into U-Boot in non-secure mode; To make code simple, it would be fine to use IH_OS_TEE for the os tyle in TPL(just like IH_OS_LINUX is using both in SPL and U-Boot).

Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE and this makes it imposible to use CONFIG_VAL(). Rename it to resolve this problem. Signed-off-by: Simon Glass <sjg@chromium.org> 2022-10-21 00:22:39 +00:00			`ldr lr, =CONFIG_TEXT_BASE`
