-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8

-First of all it shouldn't modify copied NVRAM just to make sure it can
-loop over all entries. It's enough to just compare current position
-pointer with the end of buffer address.
-Secondly buffer is guaranteed to be \0 ended, so we don't need strnchr.

-MIME-Version: 1.0

-For years we planned to get rid of old u16 fields, let's start doing it
-with MIPS code. This process will take some time, it requires doing the
-same in ssb/bcma and then switching all drivers to new fields. This will
-be handled in separated patches submitted to appropriate trees.

-Extra bcma buses may be totally different models, see following dump:

-We removed __cpuinit support (leaving no-op stubs) quite some time ago.
-However a few more crept in as of commit 6ee1d93455384cef8a0426effe85da2
-("MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)")
-
-Since we want to clobber the stubs soon, get this removed now.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This simplifies code just a bit (also maybe makes it a bit more
-intuitive?) and will allow us to stop storing header. Right now we copy
-whole NVRAM including its header to the internal buffer. It is not
-needed to store a header as we don't access all these details like CRC,
-flags, etc. The next improvement that should follow is copying only the
-real contents.

-After the big SPROM cleanup moving code to the bcm47xx_sprom_fill_auto
-we ended up with few tiny functions, two of them being identical. Let's
-get rid of these [12]-liners.
-This also stops extracting higher SPROM revisions as revision 1. Now we

- function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-To support (extract) SPROM on Broadcom ARM devices we should separate
-SPROM code and make it a separated module. We won't want to export
-bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard
-fallback function and then modify ssb to use it.

-Subject: [PATCH] ssb: reject PCI writes setting CardBus bridge resources
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If SoC has a CardBus we can set resources of device at slot 1 only. It's
-impossigle to set bridge resources as it simply overwrites device 1
-configuration and usually results in Data bus error-s.
