[PATCH 06/13] powerpc/nvram: Shuffle code around in nvram_create_partition()

From: Benjamin Herrenschmidt This error log stuff is really pseries specific. As a first step we move the initialization of these variables to the caller of nvram_create_partition(), which is also slightly reorganized so we setup the free partition before we clear the new partition, so the chance

[PATCH 13/13] powerpc/nvram: Handle partition names >= 12 chars

[PATCH 10/13] powerpc/nvram: Move the log partition stuff to pseries

From: Benjamin Herrenschmidt The nvram log partition stuff currently in nvram_64.c is really pseries specific. It isn't actually used on anything else (despite the fact that we ran the code to setup the partition on anything except powermac) and the log format is specific to pseries RTAS implemen

[PATCH 11/13] powerpc/nvram: Rename ppc64, linux partition to ibm, rtas-log

From: Benjamin Herrenschmidt I'm not aware of any userspace tool accessing it by its name anyways, it's read back by the kernel itself on the next boot to get back older log entries Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/platforms/pseries/nvram.c | 23 +--

[PATCH 09/13] powerpc/nvram: Change nvram_setup_partition() to use new helper

From: Benjamin Herrenschmidt This changes the function to use nvram_find_partition() instead of doing the lookup "by hand". It also makes some of the logic clearer and prints out more useful diagnostic information. Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/kernel/nvram_64.c | 71

[PATCH 07/13] powerpc/nvram: Improve partition removal

From: Benjamin Herrenschmidt Existing code is nasty, has bugs etc... rewrite the function more simply, and make it take the signature and optional name of the partitions to remove as arguments, thus making it a more generic utility. We also try to remove a log partition that we find and is too s

[PATCH 05/13] powerpc/nvram: Completely clear a new partition

From: Benjamin Herrenschmidt When creating a partition, we clear it entirely rather than just the first two words since the previous code was rather specific to the pseries log partition format. Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/kernel/nvram_64.c | 19 ++-

[PATCH 03/13] powerpc/nvram: nvram_create_partitions() now uses bytes

From: Benjamin Herrenschmidt This converts nvram_create_partition() to use a size in bytes rather than blocks. It does the appropriate alignment internally The size passed is also the data size (ie. doesn't include the header anymore). Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/ke
