On SuperH, the base of the physical memory might be different from
zero. In this case, PCI address zero will map to a non-zero physical
address. In order to make sure that the DMA mapping API takes care of
this DMA offset, we must fill in the dev->dma_pfn_offset field for PCI
devices. This gets done in the pcibios_bus_add_device() hook, called
for each new PCI device detected.

The dma_pfn_offset global variable is re-calculated for every PCI
controller available on the platform, but that's not an issue because
its value will each time be exactly the same, as it only depends on
the memory start address and memory size.

The code setting up the PCI -> SuperHighway mapping doesn't take into
account the fact that the address stored in PCIELARx must be aligned
with the size stored in PCIELAMRx.

For example, when your physical memory starts at 0x0800_0000 (128 MB),
a size of 64 MB or 128 MB is fine. However, if you have 256 MB of
memory, it doesn't work because the base address is not aligned on the
size.

In such situation, we have to round down the base address to make sure
it is aligned on the size of the area. For for a 0x0800_0000 base
address with 256 MB of memory, we will round down to 0x0, and extend
the size of the mapping to 512 MB.

This allows the mapping to work on platforms that have 256 MB of
RAM. The current setup would only work with 128 MB of RAM or less.

The current definition of the PCIe IO and MEM resources for SH7786
doesn't match what the datasheet says. For example, for PCIe0
0xfe100000 is advertised by the datasheet as a PCI IO region, while
0xfd000000 is advertised as a PCI MEM region. The code currently
inverts the two.

The SH4A_PCIEPARL and SH4A_PCIEPTCTLR registers allow to define the
base address and role of the different regions (including whether it's
a MEM or IO region). However, practical experience on a SH7786 shows
that if 0xfe100000 is used for LEL and 0xfd000000 for IO, a PCIe
device using two MEM BARs cannot be accessed at all. Simply using
0xfe100000 for IO and 0xfd000000 for MEM makes the PCIe device
accessible.

It is very likely that this was never seen because there are two other
PCI MEM region listed in the resources. However, for different
reasons, none of the two other MEM regions are usable on the specific
SH7786 platform the problem was encountered. Therefore, the last MEM
region at 0xfe100000 was used to place the BARs, making the device
non-functional.

This commit therefore adjusts those PCI MEM and IO resources
definitions so that they match what the datasheet says. They have only
been tested with PCIe 0.

Depending on the physical memory layout, some PCI MEM areas are not
usable. According to the SH7786 datasheet, the PCI MEM area from
1000_0000 to 13FF_FFFF is only usable if the physical memory layout
(in MMSELR) is 1, 2, 5 or 6. In all other configurations, this PCI MEM
area is not usable (because it overlaps with DRAM).

Therefore, this commit adjusts the PCI SH7786 initialization to mark
the relevant PCI resource as IORESOURCE_DISABLED if we can't use it.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Signed-off-by: Rich Felker <dalias@libc.org>

Some PCI MEM resources are marked as IORESOURCE_MEM_32BIT, which means
they are only usable when the SH core runs in 32-bit mode. In 29-bit
mode, such memory regions are not usable.

The existing code for SH7786 properly skips such regions when
configuring the PCIe controller registers. However, because such
regions are still described in the resource array, the
pcibios_scanbus() function in the SuperH pci.c will register them to
the PCI core. Due to this, the PCI core will allocate MEM areas from
this resource, and assign BARs pointing to this area, even though it's
unusable.

In order to prevent this from happening, we mark such regions as
IORESOURCE_DISABLED, which tells the SuperH pci.c pcibios_scanbus()
function to skip them.

Note that we separate marking the region as disabled from skipping it,
because other regions will be marked as disabled in follow-up patches.

In pcibios_scanbus(), we provide to the PCI core the usable MEM and IO
regions using pci_add_resource_offset(). We travel through all
resources available in the "struct pci_channel".

Also, in register_pci_controller(), we travel through all resources to
request them, making sure they don't conflict with already requested
resources.

However, some resources may be disabled, in which case they should not
be requested nor provided to the PCI core.

In the current situation, none of the resources are disabled. However,
follow-up patches in this series will make some resources disabled,
making this preliminary change necessary.

Some devices may have a non-zero DMA offset, i.e an offset between the
DMA address and the physical address. Such an offset can be encoded
into the dma_pfn_offset field of "struct device", but the SuperH
implementation of the DMA mapping API does not observe this
information.

This commit fixes that by ensuring the DMA address is properly
calculated depending on this DMA offset.

The SH7786 has different physical memory layout configurations,
configurable through the MMSELR register. The configuration is
typically defined by the bootloader, so Linux generally doesn't care.

Except that depending on the configuration, some PCI MEM areas may or
may not be available. This commit adds a helper function that allows
to retrieve the current physical memory layout configuration. It will
be used in a following patch to exclude unusable PCI MEM areas during
the PCI initialization.

  buffer.c: call thaw_super during emergency thaw
  vfs: factor sb iteration out of do_emergency_remount

This seems to cause flickering and lock-ups for a wide range of users.
Revert until we've found a proper fix for the flickering and lock-ups.

This reverts commit 36cc549d.

Hardware understands the regamma LUT as a piecewise linear function,
with points spaced exponentially along the range. We previously
programmed the LUT for range [2^-10, 2^0). This causes (normalized)
color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
end region.

For DCE, the end region is extrapolated using a single (base, slope)
pair, using the max y-value from the last point in the curve as base.
This presents a problem, since this value affects all three color
channels. Scaling down the intensity of say - the blue regamma curve -
will not affect it's end region. This is especially noticiable when
using RedShift. It scales down the blue and green channels, but leaves
full-intensity colors unshifted.

Therefore, extend the range to cover [2^-10, 2^1) by programming another
hardware segment, containing only one point. That way, we won't be
hitting the end region.

Note that things are a bit different for DCN, since the end region can
be set per-channel.
