[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] Minor cleanup
by Anders Larsen 12 Aug '05

12 Aug '05

Hi, Rick Bronson and the AT91RM9200DK is listed under PPC Systems. Since the AT91RM9200 is an ARM SoC, the attached patch against current top of CVS moves the entry to the appropriate position. Changelog: Move the AT91RM9200DK to the ARM Systems list. Cheers Anders

[U-Boot-Users] Eliminate calls of _divsi3 on ARM
by Anders Larsen 12 Aug '05

12 Aug '05

Hi, the enclosed patch agains current top of CVS eliminates two calls of the libgcc helper function _divsi3 and _modsi3. Rationale: Certain commercially available tool-chains provides b0rken libgcc.a (compiled with hardware FP) making these helper functions unusable (U-Boot already provides the unsigned counterparts in lib_arm/libarm.a). Changelog: Eliminate calls of ARM libgcc.a helper functions _divsi3 and _modsi3 Cheers Anders

[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.

by Jeff Angielski 07 Aug '05

07 Aug '05

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. CHANGELONG: * Patch by Jeff Angielski 09 Jan 2005 Fix errors that occur when accessing SystemACE CF.
