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>

Stefan thinks they don't add value.

2017-06-07Use more secure HTTPS URLs for coreboot sitesPaul Menzel
The coreboot sites support HTTPS, and requests over HTTP with SSL are also redirected. So use the more secure URLs, which also saves a request most of the times, as nothing needs to be redirected. Run the command below to replace all occurences. ``` $ git grep -l -E 'http://(www.|review.|)coreboot.org' | xargs sed -i 's,http://\(.*\)coreboot.org,https://\1coreboot.org,g' ``` Change-Id: If53f8b66f1ac72fb1a38fa392b26eade9963c369 Signed-off-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-on: https://review.coreboot.org/20034 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Georgi <pgeorgi@google.com>

Allows to use SSE and floating point in payloads without digging to much into x86 assembly code. Tested on Lenovo T500 (Intel Core2Duo). Both floating point operation and SSE is properly working.

2016-08-13libpayload: head.S: Avoid clearing BSS (and heap) againJulius Werner
3 out of 4 architectures currently zero out the payload BSS in early assembly code, which is pointless since the code loading the payload has already done that (with a more efficient memset). ARM64 has never had any code like this and can run just fine without it. This also defeats the new optimization of moving the heap out of the BSS, since all three implementations assume that everything between _edata and _end is BSS. We should just take this out.
