      ARM: fix build errors caused by selection of errata 798181 · 59fd3033
      由 Russell King 提交于 
      Several configurations are selecting errata 798181 without SMP
being selected.  This causes a warning from Kconfig:

warning: (ARCH_HIGHBANK && ARCH_KEYSTONE && SOC_OMAP5 && ARCH_TEGRA_114_SOC) selects ARM_ERRATA_798181 which has unmet direct dependencies (CPU_V7 && SMP)

The dependencies are compile time dependencies; select violates these,
resulting in:

arch/arm/kernel/built-in.o: In function `setup_processor':
psci.c:(.init.text+0x808): undefined reference to `erratum_a15_798181_init'

at build time.  Fix this by fixing the select statements for Tegra and
Highbank.

      ARM: tegra: unify Tegra's Kconfig a bit more · 20984c44
      由 Stephen Warren 提交于 
      Move all common select clauses from ARCH_TEGRA_*_SOC to ARCH_TEGRA to
eliminate duplication. The USB-related selects all should have been
common too, but were missing from Tegra114 previously. Move these to
ARCH_TEGRA too. The latter fixes a build break when only Tegra114
support was enabled, but not Tegra20 or Tegra30 support.

      ARM: tegra: convert to multi-platform · 90027225
      由 Stephen Warren 提交于 
      This allows Tegra be included in a kernel build that supports multiple
SoCs at once, which is useful for distro kernels.

This change:
* Moves Tegra's Kconfig into its own directory, as seems typical for
  multi-platform conversions.
* Stops selecting some ARM errata that are incompatible with multi-
  platform. This requires that you use a bootloader that enables the
  workaround!
* Deletes some headers and Makefile.boot that aren't needed now that we
  support multi-platform.

      ARM: tegra20: cpuidle: apply coupled cpuidle for powered-down mode · 1d328606
      由 Joseph Lo 提交于 
      The "powered-down" cpuidle mode of Tegra20 needs the CPU0 be the last one
core to go into this mode before other core. The coupled cpuidle framework
can help to sync the MPCore to coupled state then go into "powered-down"
idle mode together. The driver can just assume the MPCore come into
"powered-down" mode at the same time. No need to take care if the CPU_0
goes into this mode along and only can put it into safe idle mode (WFI).

The powered-down state of Tegra20 requires power gating both CPU cores.
When the secondary CPU requests to enter powered-down state, it saves
its own contexts and then enters WFI for waiting CPU0 in the same state.
When the CPU0 requests powered-down state, it attempts to put the secondary
CPU into reset to prevent it from waking up. Then power down both CPUs
together and power off the cpu rail.

Be aware of that, you may see the legacy power state "LP2" in the code
which is exactly the same meaning of "CPU power down".

      由 Stephen Warren 提交于 
      Move Tegra's debug-macro.S over to the common debug macro directory.

Move Tegra's debug UART selection menu into ARM's Kconfig.debug, so that
all related options are selected in the same place.

Tegra's uncompress.h is left in mach-tegra/include/mach; it will be
removed whenever Tegra is converted to multi-platform.

      ARM: tegra: simplify DEBUG_LL UART selection options · adc18315
      由 Stephen Warren 提交于 
      Delete CONFIG_TEGRA_DEBUG_UART_AUTO_SCRATCH; it's not useful any more:
* No upstream bootloader currently or will ever support this option.
* CONFIG_TEGRA_DEBUG_UART_AUTO_ODMDATA is a much more direct alternative.

Merge the fixed and automatic UART selection menus into a single choice
for simplicity; now you either pick AUTO_ODMDATA or a single fixed UART,
rather than potentially having an AUTO option override whatever fixed
option was chosen.

Remove TEGRA_DEBUG_UART_NONE; if you don't want a Tegra DEBUG_LL UART,
simply don't turn on DEBUG_LL. NONE used to be the default option, so
pick AUTO_ODMDATA as the new default.

      ARM: config: sort select statements alphanumerically · b1b3f49c
      由 Russell King 提交于 
      As suggested by Andrew Morton:

  This is a pet peeve of mine.  Any time there's a long list of items
  (header file inclusions, kconfig entries, array initalisers, etc) and
  someone wants to add a new item, they *always* go and stick it at the
  end of the list.

  Guys, don't do this.  Either put the new item into a randomly-chosen
  position or, probably better, alphanumerically sort the list.

lets sort all our select statements alphanumerically.  This commit was
created by the following perl:

while (<>) {
	while (/\\\s*$/) {
		$_ .= <>;
	}
	undef %selects if /^\s*config\s+/;
	if (/^\s+select\s+(\w+).*/) {
		if (defined($selects{$1})) {
			if ($selects{$1} eq $_) {
				print STDERR "Warning: removing duplicated $1 entry\n";
			} else {
				print STDERR "Error: $1 differently selected\n".
					"\tOld: $selects{$1}\n".
					"\tNew: $_\n";
				exit 1;
			}
		}
		$selects{$1} = $_;
		next;
	}
	if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
			  /^endif/ or /^endchoice/)) {
		foreach $k (sort (keys %selects)) {
			print "$selects{$k}";
		}
		undef %selects;
	}
	print;
}
if (%selects) {
	foreach $k (sort (keys %selects)) {
		print "$selects{$k}";
	}
}

It found two duplicates:

Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry

and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

We have four testers reporting success of this change (Tony, Stephen,
Linus and Sekhar.)
