4fe49d7bec lsxl: switch from bootm to bootz for boot commands
Use the bootz command to load zImages in case of any new boot scripts. Only
the legacy one will still use bootm. Apart form the fact, that this will
simplify the image generation process, it saves one copy of the kernel
image: Common practice is to generate an uImage with a loading address of
0x8000. This uImage contains a compressed zImage, which will unpack the
kernel image to the beginning of the RAM. But because there is already the
compressed image the uncompressor first relocates the compressed image to a
higher location. The load address is encoded into the uImage which is
generated by the distributions and thus cannot be easily changed. By using
the bootz command we can load the compressed image to a higher memory
address and the decompressor doesn't have to reloacte the image.

145df6fe2a lsxl: place the dtb below the inital ramdisk
The dtb was loaded at a memory address after the initial ramdisk. Thus a
large ramdisk would overwrite the dtb. Move it to "ramdisk_start - 64k".
64k should be enough for the device tree blob. Also the kernel
documentation arm/Booting suggests to put the dtb before the initial
ramdisk.

bc2ad9f04d lsxl: use default load addresses for legacy boot
The load addresses for the bootcmd_legacy script were taken from the
original bootloader from Buffalo. But newer kernels are too big and the
uncompressing will overwrite parts of the initial ramdisk. Therefore,
we switch to the load addresses which are also used by the other boot
script.

45e60c25b5 lsxl: convert to generic board and fix typo
Besides converting the LS-XHL and LS-CHLv2 to generic board, fix a typo
which accidentally reverted the bootsource to 'hdd' although the default
bootsource should be 'legacy'.

47539e2317 kirkwood: kconfig: refactor Kconfig and defconfig
Becuase the board select menu in arch/arm/Kconfig is too big,
move the KirkWood board select menu to kirkwood/Kconfig.

Consolidate also common settings (CONFIG_SYS_CPU="arm926ejs" and
CONFIG_SYS_SOC="kirkwood").

848fe239c6 lsxl: rework boot scripts
Move addresses for kernel, ramdisk and fdt blob to own variables. Add dtb
blob loading to all existing boot scripts, dtb filenames were taken from
vanilla kernel. Introduce new boot script bootcmd_legacy, which only loads
a kernel and a ramdisk. Make this the default boot script. This should also
restore the behaviour of the original bootloader.

3c1c68cc03 lib: rand: introduce new configs: CONFIG_LIB_RAND and CONFIG_LIB_HW_RAND
New configs:
- CONFIG_LIB_RAND    - to enable implementation of rand library in lib/rand.c
- CONFIG_LIB_HW_RAND - to enable hardware based implementations of lib rand

Other changes:
- add CONFIG_LIB_RAND to boards configs which needs rand()
- put only one rand.o dependency in lib/Makefile

CONFIG_LIB_HW_RAND should be defined for drivers which implements rand library
(declared in include/common.h):
- void srand(unsigned int seed)
- unsigned int rand(void)
- unsigned int rand_r(unsigned int *seedp)

0defddc851 config: Add a default CONFIG_SYS_PROMPT
The definitions for CONFIG_SYS_PROMPT are varied with little reason other
than to display the board name. Over half the definitions are "==> ", so
make this the default. The rest of the boards remain unchanged to avoid
breaking any external scripts expecting a certain prompt.

23c9946a3b lsxl: unset ncip for rescue mode
Instead of using the serverip we get from the DHCP server, implicitly use
the broadcast address, which is automatically set when no ncip environment
variable is set. That way it isn't necessary to use a special DHCP
configuration to set the netconsole peer.
