[U-Boot] Write to JFFS2 filesystem

Hi all, I am using u-boot 1.3.3 on a TQM885D board. Is u-boot able to write to JFFS2 file system? I was able to read a file from JFFS2 file system in flash. But I couldn't find write support for JFFS2. Is this possible from u-boot? Thanks, Jayakrishnan

[U-Boot] DHCP/BOOP command behavior

Hi all, I'm migrating from u-boot 1.0.0 to 1.3.4 and noticed that the behavior of bootp/dhcp command has changed. In 1.0.0, bootp/dhcp would just get IP setting. But in 1.3.4, they try to download the boot image using tftp after acquiring the ip from the dhcp server. How can I make it behave the

[U-Boot] [PATCH 1/1] ppc4xx: Autocalibration can set RDCC to over aggressive value.

The criteria of the AMCC SDRAM Controller DDR autocalibration U-Boot code is to pick the largest passing write/read/compare window that also has the smallest SDRAM_RDCC.[RDSS] Read Sample Cycle Select value. On some Kilauea boards the DDR autocalibration algorithm can find a large passing write
