      ARM: imx6q: let users input debug uart port number · 49c9e60e
      由 Shawn Guo 提交于 
      imx6q gets 5 uart ports in total.  Different board design may choose
different port as debug uart.  For example, imx6q-sabresd uses UART1,
imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4.  Rather than
bloating DEBUG_LL choice list with all these uart ports, the patch
introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number
when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

      ARM: imx: select HAVE_IMX_SRC when SMP is enabled · 68b25325
      由 Shawn Guo 提交于 
      With being part of multi-platform support, SMP can be enabled by other
platform even when SOC_IMX6Q is deselected.  It leads to a situation
that arch/arm/mach-imx/platsmp.c is built without HAVE_IMX_SRC selection
which will cause build error.  For example, the following link errors
will be seen when building imx5 with other v7 platforms.

 arch/arm/mach-imx/built-in.o: In function `imx_cpu_die':
 platform-ahci-imx.c:(.text+0x219c): undefined reference to `imx_enable_cpu'
 arch/arm/mach-imx/built-in.o: In function `imx_boot_secondary':
 platform-ahci-imx.c:(.cpuinit.text+0x14): undefined reference to `imx_set_cpu_jump'
 platform-ahci-imx.c:(.cpuinit.text+0x20): undefined reference to `imx_enable_cpu'

Select HAVE_IMX_SRC as long as SMP is enabled to fix the problem.

      ARM: mach-imx: Fix selection of ARCH_MXC · 4cc3c840
      由 Fabio Estevam 提交于 
      Since commit c5a0d497(ARM: imx: enable multi-platform build),
ARCH_MXC is selected by the following logic:

config ARCH_MXC
        def_bool y if ARCH_MULTI_V4_V5 || ARCH_MULTI_V6_V7

, which causes build error on vexpress_defconfig:

arch/arm/mach-imx/hotplug.c:49: undefined reference to `imx_enable_cpu'
arch/arm/mach-imx/platsmp.c:57: undefined reference to `imx_set_cpu_jump'
arch/arm/mach-imx/platsmp.c:58: undefined reference to `imx_enable_cpu'

Make ARCH_MXC a user selectable option, so that it does not get built
by default on other defconfigs that select ARCH_MULTI_V4_V5 or ARCH_MULTI_V6_V7.

      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.)

      ARM: move all dtb targets out of Makefile.boot · 360a0cab
      由 Rob Herring 提交于 
      In preparation to support multi-platform kernels, move all the dtb targets
out of the mach Makefile.boot and into the arch/arm/boot/dts/Makefile
which is closer to the sources.

DTBs are only built when CONFIG_OF is enabled and now use top level
CONFIG_ARCH_xxx instead of chip or board specific config options.
