bootm: Align cache flush end address correctly

2016-06-12T21:49:38+00:00

Flushing part of the cache should be done on cache boundaries. Trying to
flush part of a cache line is not supported and the request may be ignored
or print warnings.

Adjust the bootm code to align the end address to prevent this problem.

image: Add boot_get_fpga() to load fpga with bootm

2016-05-24T11:17:59+00:00

Add function boot_get_fpga() which find and load bitstream to
programmable logic if fpga entry is present.
Function is supported on Xilinx devices for full and partial bitstreams
in BIN and BIT format.

fdt: Allow libfdt to be used in SPL

2016-03-14T23:18:26+00:00

Add an option to enable libfdt in SPL. This can be useful when decoding
FIT files in SPL.

We need to make sure this option is not enabled in SPL by this change.
Also this option needs to be enabled in host builds. Si add a new
IMAGE_USE_LIBFDT #define which can be used in files that are built on the
host but must also build for U-Boot and SPL.

Kconfig: Move CONFIG_FIT and related options to Kconfig

2016-03-14T23:18:07+00:00

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

image: Correct the OS location code to work on sandbox

2016-02-26T15:53:10+00:00

A recent change broke the 'bootm' command on sandbox. The root cause is
using a pointer as an address. Conversion from pointer to address needs to
use map_to_sysmem() so that sandbox can do the right thing. The problem was
pre-existing but uncovered by a recent commit.

Fix this. Also move fit_get_end() to the C file to avoid needing to include
mapmem.h (and thus asm/io.h) everywhere.

bootm: fix size arg of flush_cache() in bootm_load_os().

2016-01-25T15:39:45+00:00

Variable _load_end_ points to end address of uncompressed buffer
(*not* uncomress_buffer_end / sizeof(ulong)), so multipling uncompressed
size with sizeof(ulong) is grossly incorrect in flush_cache().
It might lead to access of address beyond valid memory range and hang the CPU.

Tested on MIPS architecture by using compressed(gzip, lzma)
and uncompressed uImage.

Add support for LZ4 decompression algorithm

2015-10-11T21:12:10+00:00

This patch adds support for LZ4-compressed FIT image contents. This
algorithm has a slightly worse compression ration than LZO while being
nearly twice as fast to decompress. When loading images from a fast
storage medium this usually results in a boot time win.

Sandbox-tested only since I don't have a U-Boot development system set
up right now. The code was imported unchanged from coreboot where it's
proven to work, though. I'm mostly interested in getting this recognized
by mkImage for use in a downstream project.

net: avoid eth_unregister() call when function is unavailable

2015-09-30T02:54:45+00:00

CONFIG_NETCONSOLE causes common/bootm.c to call eth_unregister()
for network device shutdown. However, with CONFIG_DM_ETH this
function is no longer defined.

This is a workaround to avoid the call in that case, and solely
rely on eth_halt(). In case this is insufficient, a proper way
to unregister / remove network devices needs to be implemented.

Combine bootm_find_ functions together

2015-05-28T12:18:21+00:00

bootm_find_ramdisk_fdt() renamed to bootm_find_images() for readability.

The function bootm_find_ramdisk_fdt() appears to be a simple wrapper for
bootm_find_ramdisk(), bootm_find_fdt(), and now bootm_find_loadables().
I didn't see any other callers entering a bootm_find, so removing
the wrapper, and condensing these together hopefully makes the code a
little simpler.

add boot_get_loadables() to load listed images

2015-05-28T12:18:20+00:00

Added a trimmed down instance of boot_get_() to satisfy the
minimum requierments of the added feature.  The function follows the
normal patterns set by other boot_get's, which should make it a
bit easier to combine them all together into one boot_get_image()
function in a later refactor.

Documentation for the new function can be found in source:
  include/image.h
