sandbox: Use os functions to read host device tree

2014-03-18T02:05:45+00:00

At present we use U-Boot's filesystem layer to read the sandbox device tree,
but this is problematic since it relies on a temporary feauture added
there. Since we plan to implement proper block layer support for sandbox,
change this code to use the os layer functions instead. Also use the new
fdt_create_empty_tree() instead of our own code.

part_efi: fix protective mbr struct allocation

2014-02-24T15:56:07+00:00

The calloc() call was allocating space for the sizeof the struct
pointer rather than for the struct contents.
Besides, since this buffer is passed to mmc for writing and some
platforms may use cache, the legacy_mbr struct should be cache-aligned.

kbuild: use Linux Kernel build scripts

2014-02-19T16:07:50+00:00

Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

sandbox: block driver using host file/device as backing store

2014-01-09T00:24:03+00:00

Provide a way to use any host file or device as a block device in U-Boot.
This can be used to provide filesystem access within U-Boot to an ext2
image file on the host, for example.

The support is plumbed into the filesystem and partition interfaces.

We don't want to print a message in the driver every time we find a missing
device. Pass the information back to the caller where a message can be printed
if desired.

part_efi: make sure the gpt_pte is freed

2013-09-20T14:30:53+00:00

the gpt_pte wasn't being freed if it was checked against an invalid
partition. The resulting memory leakage could make it impossible
to repeatedly attempt to load non-existent files in a script.

Also, downgrade the message for not finding an invalid partition
from a printf() to a debug() so as to minimize message spam in
perfectly normal situations.

fs/ext4: fix log2blksz un-initialized error, by cacaulating its value from blksz

2013-07-22T14:09:56+00:00

The problem here is that uboot can't mount ext4 filesystem with
commit "50ce4c07df1" applied. We use hard-coded "SECTOR_SIZE"(512)
before this commit, now we introduce (block_dev_desc_t *)->log2blksz
to replace this macro. And after we calling do_ls()->fs_set_blk_dev(),
the variable log2blksz is not initialized, which it's not correct.

And this patch try to solve the problem by caculating the value of
log2blksz from variable blksz.

Fix ext2/ext4 filesystem accesses beyond 2TiB

2013-07-15T21:06:13+00:00

With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives

We now use lbaint_t for partition offset to reflect the lbaint_t change,
and access partitions beyond or crossing the 2.1TiB limit.
This required changes to signature of ext4fs_devread(), and type of all
variables relatives to block sector.

ext2/ext4 fs uses logical block represented by a 32 bit value. Logical
block is a multiple of device block sector. To avoid overflow problem
when calling ext4fs_devread(), we need to cast the sector parameter.
