treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30Z

This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42Z

Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include at all, so remove that include. Signed-off-by: Simon Glass Signed-off-by: Tom Rini

ARMv8: Allow SiP service extensions on top of PSCI code

2019-04-22T22:13:21Z

Allow PSCI layer to handle any SiP service functions added by platform vendors. PSCI layer will look for SiP service function in the SiP function table located in '._secure_svc_tbl_entries' section if the SMC function identifier is not found in the PSCI standard functions table. Use DECLARE_SECURE_SVC macro to declare and add platform specific SiP service function. This new section '._secure_svc_tbl_entries' is located next to '._secure.text' section. Refer to arch/arm/cpu/armv8/u-boot.lds. Signed-off-by: Chee Hong Ang

ARM: HYP/non-sec: allow relocation to secure RAM

2014-07-28T15:19:09Z

The current non-sec switching code suffers from one major issue: it cannot run in secure RAM, as a large part of u-boot still needs to be run while we're switched to non-secure. This patch reworks the whole HYP/non-secure strategy by: - making sure the secure code is the *last* thing u-boot executes before entering the payload - performing an exception return from secure mode directly into the payload - allowing the code to be dynamically relocated to secure RAM before switching to non-secure. This involves quite a bit of horrible code, specially as u-boot relocation is quite primitive. Signed-off-by: Marc Zyngier Acked-by: Ian Campbell
