2015-01-13x86: ivybridge: Update microcode early in bootSimon Glass
At present the normal update (which happens much later) does not work. This seems to have something to do with the 'no eviction' mode in the CAR, or at least moving the microcode update after that causes it not to work. For now, do an update early on so that it definitely works. Also refuse to continue unless the microcode update check (later in boot) is successful. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-12-18x86: Correct problems in the microcode loadingSimon Glass
There are several problems in the code. The device tree decode is incorrect in ways that are masked due to a matching bug. Both are fixed. Also microcode_read_rev() should be inline and called before the microcode is written. Note: microcode writing does not work correctly on ivybridge for me. Further work is needed to resolve this. But this patch tidies up the existing code so that will be easier. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-12-18x86: ivybridge: Update the microcodeSimon Glass
There are new microcode revisions available. Update them. Also change the format so that the first 48 bytes are not omitted from the device tree data. Signed-off-by: Simon Glass <sjg@chromium.org>
