On most i.MX* the upper bits in SW_PAD_CTL are reserved. On some chips,
like the i.MXRT1166, they are a domain write protection. Setting them to
1 can have unexpected side effects.
The device tree uses these bits for some flags. Make sure that they are
not accidentally written to some value.
The different variants of the i.MXRT have some minimal differences in
the fsl_flexspi_nor_config.h. Make sure that the header supports the
different chips.
The defines for the different clock frequencies in the
fsl_clock_config.h do not represent the clock frequencies that have been
set up in the registers. Remove them to avoid someone trusting in
correct values.
If a different chip variant is used in the i.mxrt BSP, a different
header would have to be included. Make sure that the fsl-edma driver
uses a header that doesn't have to be adapted.
The mcux_sdk has a different interface for getting the clock for
IMXRT11xx than for getting it in IMXRT10xx. Adapt simple drivers to
support that interface.
The number of GPIO devices along with each of their particular
configurations is application-specific. Encoding this information as
build options also introduced a lot of clutter.

The new amd64efi BSP supports:
- multiboot2 boot format. Runs well with GRUB.
- console based on either EFI simple text output or GOP-based framebuffer
- clock based on EFI event/timer API
- early console using either hard-wired PC-AT serial or just memory buffer
- with EFI support disabled the BSP is more or less equivalent to amd64 BSP
with multiboot2 support
The library is imported in minimalist version just to support future
amd64efi BSP.

There was a cyclic dependency: For RTEMS_STATIC_ANALYSIS we needed
basedefs.h in assert.h. For RTEMS_UNREACHABLE() we needed _Assert() from
assert.h in basedefs.h.
Fix this by introducing _Debug_Unreachable() in basedefs.h.
Add RTEMS_FUNCTION_NAME to basedefs.h and use it in basedefs.h and
assert.h.
Close#4900.
The MMU must be enabled during mapping changes and TLB invalidations.
When this is not the case, TLB updates do not occur correctly in all
cases. This is especially apparent when changing a block entry to a
table entry when remapping small memory ranges in an otherwise
contiguous block.
