This makes the assumption that setting up pinctrl in cpu_init_r() is safe.
On samus we need GPIOs before relocation in order to support power control.
This commit fixes the following message on boot:
initcall sequence ffe5c6f4 failed at call ffe01d3d (err=-1)
### ERROR ### Please RESET the board ###
In any case it seems better to leave init to driver model, so that it can
pick up the GPIO driver when it needs it. Since pinctrl is a dependency of
the GPIO driver, we may as well put the dependency there and avoid these
problems.

ARM CPUs can architecturally (speculatively) prefetch completely arbitrary
normal memory locations, as defined by the current translation tables. The
current MMU configuration for 64-bit Tegras maps an extremely large range
of addresses as DRAM, well beyond the actual physical maximum DRAM window,
even though U-Boot only needs access to the first 2GB of DRAM; the Tegra
port of U-Boot deliberately limits itself to 2GB of RAM since some HW
modules on at least some 64-bit Tegra SoCs can only access a 32-bit
physical address space. This change reduces the amount of RAM mapped via
the MMU to disallow the CPU from ever speculatively accessing RAM that
U-Boot will definitely not access. This avoids the possibility of the HW
raising SError due to accesses to always-invalid physical addresses.

We have a number of OlinuXino Lime2 boards (both NAND and eMMC versions)
which were experiencing sporadic hangs. After testing with some heavy
benchmarking and help from the Armbian forum, it was pinned down as the
DRAM settings for the board. The default is 480MHz, but this is unstable,
and even the build instructions from the vendor Olimex themselves say to
set the DRAM clock to 384. See line 96 at:
