This series adds support for warm boot, allowing the device to suspend
and resume. U-Boot sets up some 'warm boot' code in a special area such
that the SOC can find it on a resume. This code is responsible for
setting up memory and clocked and then allowing the OS to continue
where it left off.
Also included here is support for the EMC, which allows setting the memory
timings correctly in U-Boot for maximum speed operation.
Note: sign-offs are needed from Jimmy Zhang, Wei Ni and Yen Lin.
Changes in v2:
- Add check of undocumented values in hidrev register
- Add debug() output to EMC
- Add new fdtdec_locate_array() function
- Add patch to find DVC bus number
- Check error return from pmu_set_nominal() in debug mode
- Move EMC tables to device tree
- Move structs shared between A9 and AVP into warmboot.h header file
- New patch to add low-level clock functions
- Rely on compiler to optimise out debug_print_vector()
- Remove unused crypto code
- Remove unused crypto code from crypto.c
- Removed check for nominal voltage (not needed as it is done just before)
- Split PMU code into separate TPS6586X driver
- Tidy SDRAM range check in warmboot_prepare_code()
- Tidy whitespace problems
- Use const for sbox arrays
- Use low-level clock functions in warmboot code instead of register access
