[U-Boot-Users] [PATCH] add OpenGear CM4008 board support
by Greg Ungerer 12 Mar '06

12 Mar '06

Hi All, Attached is a patch that adds support to u-boot for the OpenGear CM4008 8 port console manager board. It is built around the KS8695P CPU, with 8 serial ports, 16MB RAM, and 8MB NOR flash. This patch was originally generated against u-boot 1.1.1.

[U-Boot-Users] [PATCH] revised word alignment fixes for word aligned NS16550 UART
by jean-paul.saman＠philips.com 12 Mar '06

12 Mar '06

The patch is created against current CVS 2005 march 1st and fixes problems for boards that only have word access to the NS16550 UART. OBSOLETES: From: Jean-Paul Saman Date: 23-02-2005 Subject: [PATCH] word alignment fixes for word aligned NS16550 UART peripheral CHANGELOG: * Patch by Jean-Paul Saman, 23 Feb 2005 - include/ns16550.h Fixes alignement bug with UART that only supports word aligned access: removed "__attribute__ ((packed));" for "(CFG_NS16550_REG_SIZE == 4)" GCC generates bytes access when it encounters the packed attribute regardless if the struct is already word aligned for a platform. Peripherals that can only handle word aligned access won't work properly when accessed with byte access. The struct NS16550 is already word aligned for REG_SIZE = 4, so there is no need to packed the struct in that case.

[U-Boot-Users] Suspect behaiviour if gatewayip not set
by Robin Gilks 12 Mar '06

12 Mar '06

Greetings Having played with netconsole a bit, I've observed that the current behaiviour of warning if gatewayip is not set and then using its value of zero when talking to outside the current subnet is somewhat suspect. The particular case of netconsole means that no error message is evident - it is trying to be sent the error down the ethernet connection that is being initiated with an arp(0.0.0.0)! I propose that the warning message stay but the target address is put into the arp so that a proxying router can reply to it rather then send out a nonsense arp request.

[U-Boot-Users] Patch for drivers/cfi_flash.c; properly detect write errors.
by Marcus Hall 28 Feb '06

28 Feb '06

Hello.. It seems that there is a minor problem in cfi_flash.c that prevents it from detecting that a flash write error has occurred. The first change in the attached patch is trivial, it just makes the strings output for a protected and a non-protected sector have the same length so the output looks prettier.. The second change is in flash_full_status_check(). We have just called flash_status_check() and then did a switch() on the vendor. For intel, we *should* check if there are any error bits if the previous call returned ERR_OK (Otherwise we will have output an error message in flash_status_check() already.) The original code would only check for error bits if flash_status_check() returns ERR_TIMEOUT. -- Marcus Hall marcushall(a)lucent.com *** ../u-boot-1.1.3/drivers/cfi_flash.c Sat Aug 13 17:53:35 2005 --- u-boot-1.1.3/drivers/cfi_flash.c Tue Aug 23 14:47:06 2005 *************** *** 502,508 **** if ((i % 5) == 0) printf ("\n "); printf (" %08lX%s", ! info->start[i], info->protect[i] ?

[U-Boot-Users] [PATCH] cfi_flash.c patches
by Sangmoon Kim 28 Feb '06

28 Feb '06

Hi, The two patches attached are for drivers/cfi_flash.c. cfi_flash-protect.patch adds CFG_FLASH_PROTECT_CLEAR because for some flash memories(such as 28F320C3) all banks are protected after reset. cfi_flash-buffer.patch makes write_buff not to call flash_write_cfibuffer if buffer_size is1. Because for flash memories with buffer_size 1, buffer write is not supported. Regards, Sangmoon Kim

[U-Boot-Users] [PATCH] Two System ACE CF fixes
by Peter Ryser 25 Jan '06

25 Jan '06

Attached a patch that adds support for the 16-bit wide bus of System ACE CF besides the existing support for the 8-bit wide bus. The patch also sets the FORCECFGMODE bit in the control register when the System ACE CF configuration controller is reset before reading a sector. Without this bit set System ACE CF reconfigures an FPGA if the CFGMODE pin is active whenever a sector is read. The third hunk fixes a typo. - Peter --- u-boot.orig/common/cmd_ace.c 2005-09-22 23:53:00.000000000 -0700 +++ u-boot/common/cmd_ace.c 2005-09-26 07:40:41.000000000 -0700 @@ -22,8 +22,9 @@ /* * The Xilinx SystemACE chip support is activated by defining * CONFIG_SYSTEMACE to turn on support, and CFG_SYSTEMACE_BASE - * to set the base address of the device.

[U-Boot-Users] 83xx TSEC
by David Updegraff 02 Dec '05

02 Dec '05

Hi. Anyone know of any registers to look at in the TSEC stuff that might tell a guy why a frame is not moving? Our PHY looks fine; 'mii dump' is fine, link up, etc. but in tsec_send() the buffer of a ping is loaded up, and simply never goes anywhere. ->tstat remains clear (no halt bit), but rtx.txbd[txIdx].status never changes from assigned value. Stats claim no frames; which is correct. I need some help in understanding why TSEC feels it cannot feed anything out the inerface. Thanx. -dbu.
