ARM: tegra: reduce DRAM size mapped into MMU on ARM64

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.

ARM: keystone: rename clk_get_rate() to ks_clk_get_rate()

The KeyStone platform has its own clk_get_rate() but its prototype
is different from that of the common-clk (clk-uclass) framework.

Prefix the KeyStone specific implementation with ks_ in order to
avoid name-space conflict.

8 years agokbuild: generate u-boot.cfg as a byproduct of include/autoconf.mk

kbuild: generate u-boot.cfg as a byproduct of include/autoconf.mk

Our build system still parses ad-hoc CONFIG options in header files
and generates include/autoconf.mk so that Makefiles can reference
them.  This gimmick was introduced in the pre-Kconfig days and will
be kept until Kconfig migration is completed.

The include/autoconf.mk is generated like follows:

  [1] Preprocess include/common.h with -DDO_DEPS_ONLY and
      retrieve macros into include/autoconf.mk.tmp
  [2] Reformat include/autoconf.mk.dep into include/autoconf.mk
      with tools/scripts/define2mk.sed script
  [3] Remove include/autoconf.mk.tmp

Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is
also generated by preprocessing include/config.h with -DDO_DEPS_ONLY.
In other words, there is much overlap among include/autoconf.mk and
u-boot.cfg build rules.

So, the idea is to split the build rule of include/autoconf.mk
into two stages.  The first preprocesses headers into u-boot.cfg.
The second parses the u-boot.cfg into include/autoconf.mk.  The
build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

If somebody adds references to new CONFIG options in source files,

if we run scripts/build-whitelist.sh against commit 42f75050667b,
new options CONFIG_SPL_DFU_SUPPORT and CONFIG_USB_XHCI_UNIPHIER will
appear in the list.)

In order to make steady progress of Kconfig migration, we want to
only decrease whitelist options, but never increase.

So, when we update the whitelist, we should create a temporary list,
then take the intersection of the temporary one and the current one.
