[U-Boot] [PATCH 0/8]: Fixes for ubifs build on ARM

[U-Boot] [PATCH 0/8]: Fixes for ubifs build on ARM

[Simon Kagstrom]

Hello!

This series of patches corrects some of the issues I've had with
building and using the ubifs support on ARM (and some general things).
In summary:

- move __set_bit and __clear_bit to bitops.h (was defined in ubifs.h)
- define fls for all architectures (and ffs where it was missing)
- unaligned.h was missing for ARM, add it
- use do_div from div64.h for vsprintf (avoid __udivdi3)
- use lldiv in ubifs (again to avoid __udivdi3 references)
- handle VID header offset in the ubi part command
- proper argument checking in ubifsmount

I've built and tested it on ARM (OpenRD base), but some of the patches
also affect other architectures, so please look this through!

// Simon

[U-Boot] [PATCH 1/8]: Move __set/clear_bit from ubifs.h to bitops.h

[Simon Kagstrom]

Move __set/clear_bit from ubifs.h to bitops.h

__set_bit and __clear_bit are defined in ubifs.h as well as in
asm/include/bitops.h for some architectures. This patch moves
the generic implementation to include/linux/bitops.h and uses
that unless it's defined by the architecture.

[U-Boot] [PATCH 2/8]: Define ffs/fls for all architectures

[Simon Kagstrom]

UBIFS requires fls(), which is not defined for arm (and some other
architectures) and this patch adds it. The implementation is taken from
Linux and is generic. ffs() is also defined for those that miss it.

[U-Boot] [PATCH 8/8]: Command improvements for ubifs

[Simon Kagstrom]

Check that an argument is passed to ubifsmount and that addresses and
sizes are actually numbers for ubifsload. Also improve the instructions
a bit.

This rebinds me of a patch I sent a few weeks ago (and forgot to actually push 
into u-boot-ubi):

http://article.gmane.org/gmane.comp.boot-loaders.u-boot/62440

I suggest we use my patch version since this brings the u-boot UBI version 
back in sync with the Linux version.

Best regards,
Stefan

[U-Boot] [PATCH 7/8]: Handle VID header offset in ubi part command

[Simon Kagstrom]

The VID header offset is sometimes needed to initialize the UBI
partition. This patch adds it (optionally) to the command line
for the ubi part command.

(Lines have been properly wrapped since last version)

Please explain. What has atomicity dto do with the fact if the
implementation depends on the byte order or not?

I agree that such macros should be independet of the byteorder, but
this applies to test_and_set_bit as well as to
____atomic_test_and_set_bit - why should adding "____atomic_" here
make such a difference?

Please use a consistent style: here you have an empty line between
the two #define's.

Here you don't ... and do on.

Sorry, I had to back out your patch. as it is causing compile problems:

-> ./MAKEALL voiceblue
Configuring for voiceblue board...
vsprintf.c: In function 'put_dec':
vsprintf.c:237: warning: comparison of distinct pointer types lacks a cast

Please fix and resubmit.

:(

This is because do_div() in div64.h only likes a 64bit value as first 
parameter.

So something like

--- a/lib_generic/vsprintf.c
+++ b/lib_generic/vsprintf.c
@@ -22,18 +22,19 @@ extern int do_reset (cmd_tbl_t *cmdtp, i
  #endif

  #ifdef CONFIG_SYS_64BIT_VSPRINTF
+#include <div64.h>
  # define NUM_TYPE long long
  #else
  # define NUM_TYPE long
-#endif
-#define noinline __attribute__((noinline))
-
  #define do_div(n, base) ({ \
  	unsigned int __res; \
  	__res = ((unsigned NUM_TYPE) n) % base; \
  	n = ((unsigned NUM_TYPE) n) / base; \
  	__res; \
  })
+#endif
+#define noinline __attribute__((noinline))
+

would do the trick. I don't know any clean way how to do this, though.

Best regards

I have no "better" idea as well. It's still an improvement to the current 
implementation. So I suggest you prepare a patch (IIRC, Simon is on vacation 
right now).

Thanks.

Stefan

OK. Anyway, the bitops implementation is a bit messy (which I noted
when trying to get ubifs working on arm - hence these patches). Maybe
an idea could be to bring in the Linux asm-generic/bitops/* instead and
remove the architecture-specific versions?
