ARM: rpi_b: rework boot scripts, enable sysboot

Rework rpi_b's bootcmd (and sub-commands) to match Tegra's bootcmd as
much as possible. This will aid in a future patch which will create a
common header e.g. config_distro_bootcmd.h.

While at it, enable booting from extlinux.conf using the sysboot command.

The iteration and componentization currently makes a little more sense
for Tegra than RPi, but I'd still like to keep the two as similar as
possible. USB and networking support is coming to the RPi in due course,

10 years agokbuild: change out-of-tree build
Masahiro Yamada [Tue, 4 Feb 2014 08:24:24 +0000 (17:24 +0900)]
kbuild: change out-of-tree build

This commit changes the working directory
where the build process occurs.

Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.

That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
  $(obj)u-boot.bin:  $(obj)u-boot

Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.

And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.

On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.

The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.

Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

yes

This is parsed as a string comparison of "-z" and "-z", since the check
for the binary "=" operator occurs first. Without this change, the
command would be parsed as a -z test of "-", followed by a syntax error;
a trailing -z without and operand.

This is a behavioural change, but I believe any commands affected were
previously invalid or bizarely formed.

10 years agocmd_test: use table lookup for parsing
Stephen Warren [Mon, 3 Feb 2014 20:21:02 +0000 (13:21 -0700)]
cmd_test: use table lookup for parsing

do_test() currently uses strcmp() twice to determine which operator is
present; once to determine how many arguments the operator needs, then
a second time to actually decode the operator and implement it.

Rewrite the code so that a table lookup is used to translate the operator
string to an integer, and use a more efficient switch statement to decode
and execute the operator.

This approach also acts as enablement for the following patches.

This patch should introduce no behavioural change.

fs: don't pass NULL dev_desc to most filesystems

FAT and ext4 expect that the passed in block device descriptor not be
NULL. This causes problems on sandbox, where get_device_and_partition()
succeeds for the "host" device, yet passes back a NULL device descriptor.

10 years agofs: fix generic save command implementation

fs: fix generic save command implementation

Fix a few issues with the generic "save" shell command, and fs_write()
function.

1) fstypes[].write wasn't filled in for some file-systems, and isn't
   checked when used, which could cause crashes/... if executing save
   on e.g. fat/ext filesystems.

2) fs_write() requires the length argument to be non-zero, since it needs
   to know exactly how many bytes to write. Adjust the comments and code
   according to this.

3) fs_write() wasn't prototyped in <fs.h> like other generic functions;
   other code should be able to call this directly rather than invoking
   the "save" shell command.
