2015-01-09tegra124: fix and fine tune the warm boot codeJoseph Lo
We assume that the clock rate of SCLK/HCLK/PCLK was 408MHz which was same as PLLP. But that is incorrect, BootROM had switched it to pllp_out2 with the rate 204MHz. So actually the warm boot procedure was running at the condition of SCLK=HCLK=PCLK=pllp_out2 with the rate 204MHz. And the CPU complex power on sequences were different with what we used in kernel and Coreboot. Fix up the sequence as below. * enable CPU clk * power on CPU complex * remove I/O clamps * remove CPU reset Update the time of the CPU complex power on function for record. * power_on_partition(PARTID_CRAIL): 528 uSec * power_on_partition(PARTID_CONC): 0 uSec * power_on_partition(PARTID_CE0): 4 uSec Finally, removing the redundant routine of a flow controller event with (20 | MSEC_EVENT | MODE_STOP). BUG=chrome-os-partner:29394 BRANCH=none TEST=manually test LP0 with lid switch quickly and make sure the last write to restore register successfully Original-Change-Id: Ifb99ed239eb5572351b8d896535a7c451c17b8f8 Original-Signed-off-by: Joseph Lo <josephl@nvidia.com> Original-Reviewed-on: https://chromium-review.googlesource.com/205901 Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Original-Reviewed-by: Jimmy Zhang <jimmzhang@nvidia.com> Original-Commit-Queue: Jimmy Zhang <jimmzhang@nvidia.com> (cherry picked from commit 4194a9af3999da4b061584cda9649944ec0fdfb1) Signed-off-by: Marc Jones <marc.jones@se-eng.com> Change-Id: If21d17dc888b2c289970163e4f695423173ca03d Reviewed-on: http://review.coreboot.org/8151 Reviewed-by: Ronald G.

2014-11-14tegra124: fix the dangerous VPR write orderJoseph Lo
Currently we put the VPR write code just right before the AVP is going to freeze. We have no idea does the write operation successful or not before halting the AVP. And the power_on_main_cpu should be the last step of that. So we make a fix to change the order.
