6aead23323 imx: imx8qm/qxp: Recover SPL data section for partition reboot
When doing partition reboot, the boot image won't be reloaded by ROM,
it is just CPU reset to boot entry. The SW has to keep the boot image
inside the RAM unchanged. It includes both the TEXT section and DATA
section.

For SPL, the problem is DATA section will be updated at runtime, so in
next partition reboot the data is not same as the initial value from
cold boot. If any code depends on the initial value, then it will have
problem.

This patch introduces a mechanism to recover the data section
for partition reboot. It adds a new section in image for saving
data section. When from cold boot, the data section will be saved
to that new section at SPL early phase. When from partition reboot,
the data section will be restored from the new section.

6eb32a03e0 driver: net: fm: add DM ETH support
Probe the FMan MACs based on the device tree while
retaining the legacy code/functionality.
One notable change introduced here is that, for DM_ETH,
the name of the interfaces is corrected to the fmX-macY
format, that avoids the referral to the MAC block names
which were incorrect for FMan v3 devices (i.e. DTSEC,
TGEC) and had weird formatting (i.e. FM1@DTSEC6, FM1@TGEC1).
The legacy code is left unchanged in this respect.

moves the function of reserving memory for GIC redistributor tables

This commit removes the programming sequence that enables PLLE and UPHY
PLL hardware power sequencers. Per TRM, boot software should enable PLLE
