[U-Boot] [PATCH] samsung: fix DMC1_MEM_CFG for s3c64xx
by "Seunghyeon Rhee (이승현)" 05 Dec '09

05 Dec '09

The MSB of DMC1_MEM_CFG can be set to '1' for separate CKE control for S3C6400. In the configuration of SMDK6400, however, two 16-bit mDDR (SAMSUNG K4X51163) chips are used in parallel to form 32-bit memory bus and there is no need to contorl CKE for each chip separately. AFAIK, CKE1 is not at all connected. Only CKE0 is used. Futhermore, it should be '0' always for S3C6410. When tested with a board which has a S3C6410 and the same memory configuration, a side effect is obsearved that u-boot command "reset" doesn't work leading to system hang. Leaving the bit clear is safe in most cases.

[U-Boot] [PATCH 1/3] tools/mkimage: Assume FDT image type for FIT images
by Peter Tyser 05 Dec '09

05 Dec '09

When building a Flattened Image Tree (FIT) the image type needs to be "flat_dt". Commit 89a4d6b12fd6394898b8a454cbabeaf1cd59bae5 introduced a regression which caused the user to need to specify the "-T flat_dt" parameter on the command line when building a FIT image. The "-T flat_dt" parameter should not be needed and is at odds with the current FIT image documentation. Signed-off-by: Peter Tyser <ptyser(a)xes-inc.com> --- Ideally this patch would make it into the upcoming release as its a regression. I don't really care when 2/3 and 3/3 are applied, they aren't really bug fixes. tools/mkimage.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-) diff --git a/tools/mkimage.c b/tools/mkimage.c index ab6ea32..07a9a6f 100644 --- a/tools/mkimage.c +++ b/tools/mkimage.c @@ -231,6 +231,12 @@ main (int argc, char **argv) usage (); params.datafile = *++argv; params.fflag = 1; + + /* + * The flattened image tree (FIT) format + * requires a flattened device tree image type + */ + params.type = IH_TYPE_FLATDT; goto NXTARG; case 'n': if (--argc <= 0) -- 1.6.2.1

[U-Boot] [PATCH RFC] zlib: Optimize decompression
by Joakim Tjernlund 05 Dec '09

05 Dec '09

This patch optimizes the direct copy procedure. Uses get_unaligned() but only in one place. The copy loop just above this one can also use this optimization, but I havn't done so as I have not tested if it is a win there too. On my MPC8321 this is about 17% faster on my JFFS2 root FS than the original. No speed test has been performed in u-boot. Size increase on ppc: 484 bytes Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund(a)transmode.se> --- I have the same optimization queued for linux. Figured it would be useful for u-boot too.

[U-Boot] [PATCH] add lzop decompression support
by Peter Korsgaard 05 Dec '09

05 Dec '09

Add lzop decompression support to the existing lzo bitstream handling (think gzip versus zlib), and support it for uImage decompression if CONFIG_LZO is enabled. Lzop doesn't compress as good as gzip (~10% worse), but decompression is very fast (~0.7s faster here on a slow ppc). The lzop decompression code is based on Albin Tonnerre's recent ARM Linux lzo support patch.

[U-Boot] [PATCH] Add inverted clock polarity support for Atmel LCD driver
by Dimitar Dimitrov 05 Dec '09

This is my third try for Olimex SAM9-L9260/61 board support patches.
