[ Upstream commit b9fc5320212efdfb4e08b825aaa007815fd11d16 ]

A non-zero error value likely being returned by ufshcd_scsi_add_wlus() in
case of failure of adding the WLs, but ufshcd_probe_hba() doesn't use this
value, and doesn't report this failure to upper caller.  This patch is to
fix this issue.

From: Alexandre Belloni <alexandre.belloni@bootlin.com>

[ Upstream commit ee0aa926ddb0bd8ba59e33e3803b3b5804e3f5da ]

Currently the maximum rate for peripheral clock is calculated based on a
typical 133MHz MCK. The maximum frequency is defined in the datasheet as a
ratio to MCK. Some sama5d3 platforms are using a 166MHz MCK. Update the
device trees to match the maximum rate based on 166MHz.

[ Upstream commit d71e01716b3606a6648df7e5646ae12c75babde4 ]

If, for some bizarre reason, the compiler decided to split up the write
of STE DWORD 0, we could end up making a partial structure valid.

Although this probably won't happen, follow the example of the
context-descriptor code and use WRITE_ONCE() to ensure atomicity of the
write.

[ Upstream commit 76950f7162cad51d2200ebd22c620c14af38f718 ]

To perform the reserve_crashkernel() operation kexec uses SECTION_SIZE to
find a memblock in a range.
SECTION_SIZE is not defined for nommu systems. Trying to compile kexec in
these conditions results in a build error:

  linux/arch/arm/kernel/setup.c: In function ‘reserve_crashkernel’:
  linux/arch/arm/kernel/setup.c:1016:25: error: ‘SECTION_SIZE’ undeclared
     (first use in this function); did you mean ‘SECTIONS_WIDTH’?
             crash_size, SECTION_SIZE);
                         ^~~~~~~~~~~~
                         SECTIONS_WIDTH

     is reported only once for each function it appears in
  linux/scripts/Makefile.build:265: recipe for target 'arch/arm/kernel/setup.o'

Make KEXEC depend on MMU to fix the compilation issue.
