[U-Boot-Users] Patches for ARM IntegratorCP, ARM926EJS, and ARM946ES
by Shawn Jin 12 Aug '05

12 Aug '05

Hi, The patches were developed on an ARM IntegratorCP board with ARM946ES. Since the majority code of ARM946ES cpu was copied from ARM926EJS and there was bug about CFG_HZ found in ARM946ES later, I also fixed this CFG_HZ error on ARM926EJS. The major changes are 1. Mulitple core modules support (u-boot.multicm.patch) Following OMAP boards' methodology, I added mulitple core module configuration. For example, integratorcp_946es_config is for IntegratorCP board with ARM946ES, integratorcp_config is for IntegratorCP board with ARM926EJS by default, integratorap_946es_config is for IntegratorAP board with ARM946ES, and integratorap_config is for IntegratorAP with ARM926EJS. Now only two core modules are supported, ARM946ES and ARM926EJS. 2. ARM946ES support (u-boot.arm946es.patch) 3. ARM926EJS bug fix (u-boot.arm926ejs.patch) Fixed CFG_HZ problem. Set CFG_HZ to 1000. The solution is from AT91RM9200. 4. IntegratorCP bug fixes (u-boot.integratorcp.patch) Added SDRAM size information and FLASH support. Philippe, I don't have an ARM926EJS core module. Would you please test the CFG_HZ fix on your system? Thanks. Regards, -Shawn.

[U-Boot-Users] [patch]fixes for cmd_fpga.c
by Andrew Dyer 08 Aug '05

08 Aug '05

The attached patch: 1) fixes a bug with the 'fpga loadb' command The bug is in calculating the config data size - 4 bytes of length info were being read as signed chars, casted to long, shifted and added. The cast to long was doing sign extension and causing an incorrect result if a byte was greater than 0x80. For me this caused the fpga load to end early and time out waiting for the hardware completion. 2) removes compilation warnings about using __FUNCTION__ concatenated with strings 3) changes the fpga loadb to always print the file header info during a load. I realize this patch is a mishmash - hopefully it's helpful to someone. -- Hardware, n.: The parts of a computer system that can be kicked.

Attached is a patch that fixes the configuration controller errors that sometimes occur when accessing the SystemACE CF. The patch also fixes the locking routines so that they do not stomp on the other bits in the controller register. Finally, the patch will auto detect the partition type to prevent "Partition x not valid on device y" error messages.

[U-Boot-Users] SCSI support for MIB405 board
by Wolfgang Denk 04 Aug '05

04 Aug '05

Dear Denis, can you tell me something about the SCSI support in the current versions of U-Boot? It seems the MIB405 board (maintained by you) has SCSI support enabled, but the whole code in common/cmd_scsi.c seemd to be unused - for example, there is no caller of do_scsi() or do_scsiboot() anywhere in the whole source tree? Best regards, Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de In general, they do what you want, unless you want consistency. - Larry Wall in the perl man page
