2015-04-03program loading: unify on struct progAaron Durbin
Instead of having different structures for loading ramstage and payload align to using struct prog. This also removes arch_payload_run() in favor of the prog_run() interface.

2015-04-03program loading: add prog_run() functionAaron Durbin
The prog_run() function abstracts away what is required for running a given program. Within it, there are 2 calls: 1. platform_prog_run() and 2. arch_prog_run(). The platform_prog_run() allows for a chipset to intercept a program that will be run. This allows for CPU switching as currently needed in t124 and t132.

2015-04-03program loading: introduce struct progAaron Durbin
The struct prog serves as way to consolidate program loading. This abstraction can be used to perform more complicated execution paths such as running a program on a separate CPU after it has been loaded. Currently t124 and t132 need to do that in the boot path. Follow on patches will allow the platform to decide how to execute a particular program. Note: the vboot path is largely untouched because it's already broken in the coreboot.org tree. After getting all the necessary patches pushed then vboot will be fixed.

2015-04-02mips: do not place branch instructions in branch delay slotVadim Bendebury
A branch instruction in a branch delay slot confuses the execution pipeline and causes an exception. bootblock.S was written 'by hand', has a branch instruction in branch delay slot and includes '.set noreorder' directive, which causes it to crash when trying to branch to main(). Adding a nop instruction fixes the problem. Also adding a nop after the last branch in the file just in case main() returns and the object linked next starts with a branch. BUG=chrome-os-partner:31438 TEST=Running on the simulator can reach main() now Change-Id: I0882b2eb5ce426f5a311018ffbb6f37a2ca64d98 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/221421 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/9183 Reviewed-by: Ronald G.

2015-03-30mips: Simplify architecture specific Makefile.incPatrick Georgi
The mips Makefile was inherited from x86 and so included lots of stuff that is necessary on x86 but nowhere else. That cruft is now gone. It also adopts the non-x86 approach of handling linker scripts, hardcoding an include to ldoptions there, instead of manual concatenation (of just one file plus options). This is inspired by the commit listed below, but rewritten to match upstream, and split in smaller pieces to keep intent clear.
