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>
2017-03-08libpayload-x86: Enable SSE and FPU when presentPatrick Rudolph
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.

2017-02-17libpayload: x86/head - implement argc/argv handlingMathias Krause
Implement the argc/argv passing as described in coreboot’s payload API: http://www.coreboot.org/Payload_API While at it, give the code some love by not needlessly trashing register values.

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.
