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 <marc.zyngier@arm.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> |
