fs: Kconfig: Add a separate option for FS_CRAMFS

2017-04-30T17:40:59+00:00

Rather than using CMD_CRAMFS for both the filesystem and its command, we
should have a separate option for each. This allows us to enable CRAMFS
support without the command, if desired, which reduces U-Boot's size
slightly.

fs: Kconfig: Add a separate config for FS_CBFS

Rather than using CMD_CBFS for both the filesystem and its command, we
should have a separate option for each. This allows us to enable CBFS
support without the command, if desired, which reduces U-Boot's size

ext4: Fix comparision of unsigned expression with < 0

2017-04-27T20:49:09+00:00

In file ext4fs.c funtion ext4fs_read_file() compares an
unsigned expression with < 0 like below

	lbaint_t blknr;
	blknr = read_allocated_block(&(node->inode), i);
	if (blknr < 0)
		return -1;

blknr is of type ulong/uint64_t. read_allocated_block() returns
long int. So comparing blknr with < 0 will always be false. Instead
declare blknr as long int.

Similarly ext4/dev.c does a similar comparison. Drop the redundant
comparison.

cramfs: basic symlink support

2017-04-18T14:27:58+00:00

Handle symlinks to files in the current directory. Other cases could be
handled with additional code, but this is a start.

Add explicit errors for absolute paths and links found in the middle of
a path (directories). Other cases like '..' or '.' will result with the
file not being found as when those path components are explicitly
provided.

Add a helper to decompress a null-terminated link name which is shared
with cramfs_list_inode.

cramfs: block pointers are 32 bits

2017-04-18T14:27:57+00:00

Using a variably-sized type is incorrect here since we're reading a
fixed file format. Fixes cramfs on 64-bit platforms.

flash: complete CONFIG_SYS_NO_FLASH move with renaming

2017-02-12T19:30:25+00:00

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.

During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH".  Flipping the logic will
make the code more readable.  Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.

This commit was created as follows:

[1] Edit "default n" to "default y" in the config entry in
    common/Kconfig.

[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"

[3] Rename the instances in defconfigs by the following:
  find . -path './configs/*_defconfig' | xargs sed -i \
  -e '/CONFIG_SYS_NO_FLASH=y/d' \
  -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

[4] Change the conditionals by the following:
  find . -name '*.[ch]' | xargs sed -i \
  -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
  -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
  -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
  -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'

[5] Modify the following manually
  - Rename the rest of instances
  - Remove the description from README
  - Create the new Kconfig entry in drivers/mtd/Kconfig
  - Remove the old Kconfig entry from common/Kconfig
  - Remove the garbage comments from include/configs/*.h

fs/fat: Fix unaligned __u16 reads for FAT12 access

2017-01-28T19:04:51+00:00

Doing unaligned reads is not supported on all architectures, use
byte sized reads of the little endian buffer.
Rename off16 to off8, as it reflects the buffer offset in byte
granularity (offset is in entry, i.e. 12 bit, granularity).
Fix a regression introduced in 8d48c92b45aea91e2a2be90f2ed93677e85526f1

cmd, disk: convert CONFIG_PARTITION_UUIDS, CMD_PART and CMD_GPT

2017-01-28T13:48:03+00:00

We convert CONFIG_PARTITION_UUIDS to Kconfig first.  But in order to cleanly
update all of the config files we must also update CMD_PART and CMD_GPT to also
be in Kconfig in order to avoid complex logic elsewhere to update all of the
config files.

fs/ext4: Initialize group descriptor size for revision level 0 filesystems

genext2fs creates revision level 0 filesystems, which are not readable
by u-boot due to the initialized group descriptor size field.
