Here are more patches in the progression towards multiplatform, sparse
irq conversions in particular.
Tegra has a handful of cleanups and general groundwork, but is
not quite there yet on full enablement.
Platforms that are enabled through this branch are VT8500 and Zynq. note
that i.MX was converted in one of the earlier cleanup branches as
well (before we started a separate topic for multiplatform). And both
new platforms for this merge window, sunxi and bcm, were merged with
multiplatform support enabled.

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.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
In order to move Tegra's debug-macro.S to a common location for single
zImage, it must not rely on any machine-specific header files such as
<mach/iomap.h>. Duplicate the few physical address definitions that
debug-macro.S relies upon directly into the file.
To avoid tegra_io_desc[] requiring shared knowledge of the UART
mapping's virtual address, use a virtual address outside the ranges
in tegra_io_desc[]. Call debug_ll_io_init() to propagate the mapping
beyond the early pages tables.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
Prior to this change, Tegra's debug-macro.S relied on uncompress.h having
determined which UART to use, and whether it was safe to use the UART
(i.e. is it not in reset, and is clocked). This determination was
communicated from uncompress.h to debug-macro.S using a few bytes of
Tegra's IRAM (an on-SoC RAM). This had the disadvantage that uncompress.h
was a required part of the kernel boot process; booting a non-compressed
kernel would not allow earlyprintk to operate.
This change duplicates the UART selection and validation logic into
debug-macro.S so that the reliance on uncompress.h is removed.
This also helps out with single-zImage work, since there is currently no
support for using any uncompress.h with single-zImage.

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.

SPARSE_IRQ is required for single zImage support.
With this enabled, we can delete <mach/irqs.h>. This requires removing
one unnecessary include of that file, and hard-coding the PCIe IRQ into
the PCIe driver. This is a hack that will be dealt with as part of
converting the PCIe driver into a true DT-supporting driver.

The L2 RAM is in different power domain from the CPU cluster. So the
L2 content can be retained over CPU suspend/resume. To do that, we
need to disable L2 after the MMU is disabled, and enable L2 before
the MMU is enabled. But the L2 controller is in the same power domain
with the CPU cluster. We need to restore it's settings and re-enable
it after the power be resumed.

This is a power gating idle mode. It support power gating vdd_cpu rail
after all cpu cores in "powered-down" status. For Tegra30, the CPU0 can
enter this state only when all secondary CPU is offline. We need to take
care and make sure whole secondary CPUs were offline and checking the
CPU power gate status. After that, the CPU0 can go into "powered-down"
state safely. Then shut 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".

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,

and partly because of constantly developed ASoC and ARM stuff.
Some highlights:
- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later
- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)
- HD-audio controller got the support of runtime PM and the support of
D3 clock-stop. Also changing the power_save option in sysfs kicks
off immediately to enable / disable the power-save mode.
- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in HD-audio
are continued cleanups and standardization for the generic auto
parser and bug fixes (HBR, device-specific fixups), in addition to
the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the

firmware loading code. Other than that, most of changes in
HD-audio are continued cleanups and standardization for the generic
auto parser and bug fixes (HBR, device-specific fixups), in
addition to the support of channel-map API.
- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.
- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
- Enhancements to the ux500 and wm2000 drivers
- A new driver for DA9055 and the support for regulator bypass mode."

This time the IOMMU updates contain a bunch of fixes and cleanups to
various IOMMU drivers and the DMA debug code. New features are the
code for IRQ remapping support with the AMD IOMMU (preperation for that
was already merged in the last release) and a debugfs interface to
export some statistics in the NVidia Tegra IOMMU driver.

Since the complete conversion to device tree, there are no board-

The PL310_ERRATA_753970 and ARM_ERRATA_764369 symbols only make sense
when the base features for them are enabled, so select them
conditionally in Kconfig to avoid warnings like:
warning: (UX500_SOC_COMMON) selects PL310_ERRATA_753970 which has unmet direct dependencies (CACHE_PL310)
warning: (ARCH_TEGRA_2x_SOC && ARCH_TEGRA_3x_SOC && UX500_SOC_COMMON) selects ARM_ERRATA_764369 which has unmet direct dependencies (CPU_V7 && SMP)
