      ARM: dts: Fix missing GPMC NAND device width for omap3 boards · 24f284af
      Tony Lindgren authored
      Looks like we have some GPMC NAND timings missing device
      width. This fixes "gpmc_cs_program_settings: invalid width 0!"
      errors during boot.

      ARM: dts: Use better omap GPMC timings for LAN9220 · 13aec8e4
      Tony Lindgren authored
      With the GPMC warnings now enabled, I noticed the LAN9220 timings
      can overflow the GPMC registers with 200MHz L3 speed. Earlier we
      were just skipping the bad timings and would continue with the
      bootloader timings. Now we no longer allow to continue with bad
      timings as we have the timings in the .dts files.
      
      We could start using the GPMC clock divider, but let's instead
      use the u-boot timings that are known to be working and a bit
      faster. These are basically the u-boot NET_GPMC_CONFIG[1-6]
      defines deciphered. Except that we don't set gpmc,burst-length
      as that's only partially configured and does not seem to work
      if fully enabled.
      
      [tony@atomide.com: updated to remove gpmc,burst-length]

      ARM: dts: Add GPMC timings for omap zoom serial port · b5399ea8
      Tony Lindgren authored
      The four port serial port on the zoom debug board uses a TL16CP754C
      with a single interrupt and GPMC chip select. The serial ports each
      use a 8 bytes for IO registers, and are 256 bytes apart on the GPMC
      line.
      
      Let's add timings for all four ports so we can remove the GPMC
      workarounds for using bootloader timings.
      
      Not caused by this patch, but looks like u-boot only properly
      initializes the fifo on the first serial port. Currently the other
      ports produce garbage at least with my version of u-boot. I suspect
      that TL16CP754C needs non-standard initialization added to 8250
      driver to properly fix this issue.

      ARM: dts: Fix wrong GPMC size mappings for omaps · e2c5eb78
      Tony Lindgren authored
      The GPMC binding is obviously very confusing as the values
      are all over the place. People seem to confuse the GPMC partition
      size for the chip select, and the device IO size within the GPMC
      partition easily.
      
      The ranges entry contains the GPMC partition size. And the
      reg entry contains the size of the IO registers of the
      device connected to the GPMC.
      
      Let's fix the issue according to the following table:
      
      Device          GPMC partition size     Device IO size
      connected       in the ranges entry     in the reg entry
      
      NAND            0x01000000 (16MB)       4
      16550           0x01000000 (16MB)       8
      smc91x          0x01000000 (16MB)       0xf
      smc911x         0x01000000 (16MB)       0xff
      OneNAND         0x01000000 (16MB)       0x20000 (128KB)
      16MB NOR        0x01000000 (16MB)       0x01000000 (16MB)
      32MB NOR        0x02000000 (32MB)       0x02000000 (32MB)
      64MB NOR        0x04000000 (64MB)       0x04000000 (64MB)

      ARM: dts: Fix bootloader version dependencies by muxing n900 smc91x pins · 9a894953
      Tony Lindgren authored
      Apparently some versions of nolo don't mux the all the necessary GPMC
      pins for the smc91x probe to work properly. Let's fix this issue
      by adding mux support for GPMC to the kernel.
      
      Note that GPMC clk needs input enabled for OnenNAND to work.

       "This is a pretty large update.  I think it is roughly as big as what I
        usually had for the _whole_ rc period.
      
        There are a few bad bugs where the guest can OOPS or crash the host.
        We have also started looking at attack models for nested
        virtualization; bugs that usually result in the guest ring 0 crashing
        itself become more worrisome if you have nested virtualization,
        because the nested guest might bring down the non-nested guest as
        well.  For current uses of nested virtualization these do not really
        have a security impact, but you never know and bugs are bugs
        nevertheless.
      
        A lot of these bugs are in 3.17 too, resulting in a large number of
