From comparison of current logic and the logic that was prior to commit
aba27acf, we see that first parameter of FPGA_GET_REG() shall be the
FPGA index and not channel number. The re-factoring in commit aba27acf
accidentally changed that.

Currently, U-Boot behaves as follows:

- Begin with no SD card inserted in "mmc 1"
- Execute: mmc dev 1
- This fails, since there is no card
- User plugs in an SD card
- Execute: mmc dev 1
- This still fails, since the HW isn't reprobed.

With this change, U-Boot behaves as follows:

- Begin with no SD card inserted in "mmc 1"
- Execute: mmc dev 1
- This fails, since there is no card
- User plugs in an SD card
- Execute: mmc dev 1
- The newly present SD card is detected

I know that "mmc rescan" will force the HW to be reprobed, but I feel it
makes more sense if "mmc dev" always reprobes the HW after selecting the
current MMC device. This allows scripts to just execute "mmc dev", and
not have to also execute "mmc rescan" to check for media presense.

The body of init_mmc_device() is now identical to that of do_mmc_rescan()
except for the error codes returned. Modify do_mmc_rescan() to simply
call init_mmc_device() and convert the error codes, to avoid code

This allows callers to inject mmc->has_init = 0 between finding the
MMC device, and calling mmc_init(), which forces mmc_init() to rescan
the HW. Future changes will use this feature.

Currently, get_device()/get_dev_hwpart() for MMC devices does not select
an explicit HW partition unless the user explicitly requests one, i.e. by
requesting device "mmc 0.0" rather than just "mmc 0". I think it makes
more sense if the default is to select HW partition 0 (main data area)
if the user didn't request a specific partition. Otherwise, the following
happens, which feels wrong:

Select HW partition 1 (boot0):
mmc dev 0 1

Attempts to access SW partition 1 on HW partition 1 (boot0), rather than
SW partition 1 on HW partition 0 (main data area):
ls mmc 0:1 /

With this patch, the second command above re-selects the main data area.

Many device types don't support HW partitions at all, so if HW partition
0 is selected (either explicitly or as the default) and there's no
select_hwpart function, we simply skip attempting to select a HW
partition.

Some MMC devices (i.e. SD cards) don't support HW partitions. However,
this patch still works, since mmc_start_init() sets the current
partition number to 0, and mmc_select_hwpart() succeeds if the requested
partition is already selected.

Currently, "mmc dev 0" does not change the selected HW partition. I
think it makes more sense if "mmc dev 0" is an alias for "mmc dev 0 0",

if the user didn't request a specific partition. Otherwise, the following

Select HW partition 1 (boot0):

Doesn't change the HW partition, so it's still 1 (boot0):

Rather than just returning -1 everywhere, try to return something
meaningful from mmc_select_hwpart(). Note that most other MMC functions
don't do this, including functions called from mmc_select_hwpart(), so
I'm not sure how effective this will be. Still, it's one less place with
hard-coded -1.

It seems the code tries to trick the compiler the argument

fool them so easily an now warn. Gcc and clang don't seem

GCC on Cygwin generates executables with .exe extension,
for example:

Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

"SFX = .exe" was originally added for Cygwin environment.

It is true that GCC on Cygwin spits executables with .exe extention.

For example,

  gcc -o foo foo.c

will generate "foo.exe", not "foo".

But GNU make is also nicely adjusted for Cygwin.

For example,

  foo: foo.c
          gcc -o $@ $<

will compare the timestamp between "foo.exe" and "foo.c".

You do not have to tweak Makefiles like this:

  foo$(SFX): foo.c
          gcc -o $@ $<

And "make clean" works as well without adjustment for Cygwin because
the command "rm foo" on Cygwin will delete both "foo" and "foo.exe".

In conclusion, makefiles do not need special care for Cygwin.

Bug: SDCard with a messed up partition but still has a FAT signature
intact is readable in Linux but unreadable in uboot with 'fatls'.

Fix: When partition info checking fails, there is no checking for a
FAT signature (DOS_PBR) which will fail 'fatls'. FAT signature checking
is done when no valid partition is found in partition table. If FAT
signature is found, the disk will be read as PBR and continue
processing.
