sama7g5 and other SoCs (sama5d3, sam9x60) define in the Reset Controller
a RSTC_CR.EXTRST bit that asserts the nrst_out pin which resets external
devices.
This is particular useful for external devices that are configured in
stateful modes which can not be undone without reconfiguring the device
or without resetting the device. An example is an SPI NOR flash that is
configured in octal mode. The do_reset u-boot cmd does not call any
driver's remove method, but merely resets the CPU. As the code was, this
left the flash in octal mode, being impossible for the first stage boot
loaders to recover/identify the flash after a "software reset".
RSTC_CR.EXTRST comes in handy here, as it can be set at "software reset"
to assert low the nrst_out pin during a time defined by the RSTC_MR.ERSTL
field and reset the external devices (including the SPI NOR flash in the
example).
nrst_out is always asserted at "user reset" and it resets the external
devices correctly. Asserting nrst_out at "software reset" should behave
in a similar way. The only difference that I could find between the two
types of resets in regards to the nrst_out signal, is that at "user reset"
timing diagram the "Processor and Peripherals Reset Line" rises after six
MD_SLCK cycles after the nrst_out line rose, while at the "software reset"
timing diagram the "Processor and Peripherals Reset Line" is active for
3 MD_SLCK cycles + 2 MCK cycles. In other words, in the "software reset"
case the nrst_out signal can be active for a longer period of time than the
"Processor and Peripherals Reset Line" active time, depending on the
RSTC_MR.ERSTL value.
Using the default value (zero) for RSTC_MR.ERSTL, worked just fine for the
sama7g5 case. Tested QSPI0 and GMAC0/GMAC1 on sama7g5ek rev 4 after a
software reset with RSTC_CR.EXTRST=1 and RSTC_MR.ERSTL=0.

Convert AT91RESET_EXTRST to Kconfig for easier integration. The symbol is
not configurable from menuconfig, it will be automatically selected by SoCs
that select it explicitly via the "select" directive.
AT91RESET_EXTRST sets the Reset Controller's RSTC_CR.EXTRST bit which
asserts the nrst_out pin that resets external devices.

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.
As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config
node), all the lingering definitions in header files will cause
warnings/errors due to the redefinition of the configuration item.
As we don't want to pollute the defconfig files (and values should
usually be identical for entire architectures), the defaults are moved
into Kconfig. Kconfig will always pick the first default that
matches, so please keep these values at the end of each file (to allow
any board-specific Kconfig, which will be included earlier) to
override with an unconditional default setting.
