[PATCH v1 00/11] Add SSP/TSP power control and DRAM remap support for AST2700

[Jamin Lin via <qemu-arm@nongnu.org>]

This series improves AST2700 platform support by aligning SSP/TSP
power and reset behavior with hardware, and enabling DRAM remapping
required for proper firmware boot flow.

v1:
  1. The changes move DRAM/SDMC initialization earlier to support memory
aliasing, add DRAM aliases for SSP/TSP SDRAM remap, and implement
SSP/TSP reset, power-on, and remap controls via SCU registers.
  2. With these updates, SSP and TSP can be booted via PSP and load their
binaries from DRAM. Functional tests and documentation are updated
accordingly.
