dt/flattree: explicitly pass command line pointer to early_init_dt_scan_chosen

2011-05-11T12:53:18+00:00

This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument.  Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.

dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()

2011-01-16T05:01:58+00:00

The physical address is never used by the device tree code when
allocating memory for unflattening.  Change the architecture's alloc
hook to return the virutal address instead.

microblaze: Remove useless early_init_dt_check_for_initrd

Remove copy&paste error. Microblaze doesn't support initrd.

of/flattree: Eliminate need to provide early_init_dt_scan_chosen_arch

2010-10-21T17:10:10+00:00

This patch refactors the early init parsing of the chosen node so that
architectures aren't forced to provide an empty implementation of
early_init_dt_scan_chosen_arch.  Instead, if an architecture wants to
do something different, it can either use a wrapper function around
early_init_dt_scan_chosen(), or it can replace it altogether.

This patch was written in preparation to adding device tree support to
both x86 ad MIPS.

microblaze: Add support for little-endian Microblaze

2010-10-21T05:51:59+00:00

Microblaze little-endian toolchain exports __MICROBLAZEEL__
which is used in the kernel to identify little/big endian.

The most of the changes are in loading values from DTB which
is always big endian.

Little endian platforms are based on new AXI bus which has
impact to early uartlite initialization.

microblaze: Support early console on uart16550

2010-10-21T05:51:53+00:00

Early console support reuse setting from U-BOOT that's why
it is not necessary to setup baudrates, etc.

lmb: rename to memblock

2010-07-14T07:14:00+00:00

via following scripts

      FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

      sed -i \
        -e 's/lmb/memblock/g' \
        -e 's/LMB/MEMBLOCK/g' \
        $FILES

      for N in $(find . -name lmb.[ch]); do
        M=$(echo $N | sed 's/lmb/memblock/g')
        mv $N $M
      done

and remove some wrong change like lmbench and dlmb etc.

also move memblock.c from lib/ to mm/

of: move definition of of_chosen into common code.

2010-02-14T14:13:55+00:00

Rather than defining of_chosen in each arch, it can be defined for all
in driver/of/base.c
