2023-05-24libpayload/arch/x86: Update API handling of CBTABLE handoffMaximilian Brune
The payload API of coreboot described in https://www.coreboot.org/Payload_API does not reflect the current handoff mechanism to hand the coreboot tables off. Therefore the arguments supplied by coreboot (cbtable) will currently never be parsed correctly and libpayload has to search for the coreboot tables by iterating through memory. This patch removes the old payload API implementation and just takes the coreboot table pointer from the first argument on the stack. Tested: started prodrive/atlas with coreinfo payload Signed-off-by: Maximilian Brune <maximilian.brune@9elements.com> Change-Id: I51fb0cfc81043cbfe3fc9c8ea0776add2d6a42b2 Reviewed-on: https://review.coreboot.org/c/coreboot/+/74965 Reviewed-by: Julius Werner <jwerner@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2020-07-08libpayload: arm64: silence libpayload main entryMichael Walle
No other architecture in libpayload outputs anything in the main entry routine. Let alone an exception test which looks like a real exception to the normal user and is most likely really misleading. Silence the startup code.

2015-03-21libpayload arm64: Initialize and enable MMUFurquan Shaikh
What this change does: 1) Initialize limited page tables as soon as we jump into libpayload. Basically two ranges are initialized. One is for the BASE_ADDRESS and other is for the coreboot_tables. With page tables initialized and MMU enabled, we jump into code to parse coreboot tables. 2) Once coreboot tables are parsed and we have complete picture of the memory, we perform a complete page table initialzation and enable MMU and then jump to payload. Additionally, we also: 1) Initialize DMA memory on our own depending upon the memory map. It ensures that the DMA buffer is placed in 32-bit memory.
