2012-04-05ARM: tegra: rethink the cpu suspend-resume code pathVarun Wadekar
The current kernel methodology expects that tegra_cpu_suspend is actually the last function in the entire suspend sequence. In order to achieve this, the code needs to be remodelled a bit so that we actually execute native cpu_suspend at the end of the suspend sequence. This allows us to leverage all the cpu_suspend code developed by ARM in the upstream kernels.

2011-11-30ARM: tegra: pm: Do not use ioremap for sys memPrashant Gaikwad
ARMv6+ architecture does not allow ioremap on system memory. lp0 is relocated using ioremap on DRAM. If lp0 vector start address is in system memory then use memblock_reserve and do not relocate. Else if it is overlapping with carveout/fb then first remove the carveout/fb using memblock_remove and then use ioremap.

2011-11-30arm: tegra: pm: Relocate lp0 vectorPrashant Gaikwad
LP0 vector is allocated by BL and address is shared to kernel. For platform with memory less than 1GB it was allocated in the overlapping region of carveout memory. Because of it during AVP operation it gets corrupted, which prevents resume. Relocate AVP vector to some other location where overlapping will not occur.
