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

+
+Some ARM cores are not capable to run in ARM mode (e.g. Cortex-M3). So
+obviously these cannot enter the kernel in ARM mode. Make an exception
+for them and let them enter in THUMB mode.

+Both calls are identical currently. This patch prepares to deprecate

+Also move an unconditional usage of read_cpuid_cachetype to a more local

+
+Traditionally for !CPU_CP15 read_cpuid and read_cpuid_ext returned the
+processor id independent of the parameter passed in. This is wrong of
+course but theoretically this doesn't harm because it's only called on
+machines having a cp15.
+
+Instead return 0 unconditionally which might make unused code paths be

+
+This allows to put the filesystem at a defined address in ROM allowing

+
+I think it's safe to default to ROM because the intention of using the
+uclinux map is to use a romfs and so mtd-ram doesn't give you anything
+that mtd-rom doesn't.

+I was (at least) the second person trying to fix a warning by sparse, so
+document in the code why this is a bad idea and add an extern declaration to
+make sparse happy.

-
- - select NO_IOPORT + don't provide __io()
- - fix debug-macro stuff to do proper fifo handling, fix register
-   names and enable TX as the driver disables it occasionally
- - add DEBUG_EFM32_UART1
- - $SUBJECT ~= s/architecture/platform/
- - a timekeeping fix
- - #include "common.h" instead of <common.h> in time.c
