[U-Boot-Users] Patch: Changes to support GCC 3.3.x
by Yuli Barcohen 14 Mar '04

14 Mar '04

GCC 3.3.x changed handling of global variables explicitly initialised to zero. It puts them to .bss section and not .data as it was in older GCC versions. This change breaks environment redundancy feature. Attached patch fixes the problem. -- ======================================================================== Yuli Barcohen | Phone +972-9-765-1788 | Software Project Leader yuli(a)arabellasw.com | Fax +972-9-765-7494 | Arabella Software, Israel ======================================================================== Index: common/env_flash.c =================================================================== RCS file: /home/CVS/u-boot/u-boot/common/env_flash.c,v retrieving revision 1.1.1.3 diff -p -u -r1.1.1.3 env_flash.c --- common/env_flash.c 16 Jul 2003 11:23:42 -0000 1.1.1.3 +++ common/env_flash.c 4 Mar 2004 13:50:24 -0000 @@ -79,9 +79,9 @@ static env_t *flash_addr_new = (env_t *) static ulong end_addr = CFG_ENV_ADDR + CFG_ENV_SECT_SIZE - 1; static ulong end_addr_new = CFG_ENV_ADDR_REDUND + CFG_ENV_SECT_SIZE - 1; -static uchar active_flag = 1; -static uchar obsolete_flag = 0; -#endif +#define ACTIVE_FLAG 1 +#define OBSOLETE_FLAG 0 +#endif /* CFG_ENV_ADDR_REDUND */ extern uchar default_environment[]; extern int default_environment_size; @@ -127,12 +127,12 @@ int env_init(void) gd->env_addr = addr_default; gd->env_valid = 0; } - else if (flag1 == active_flag && flag2 == obsolete_flag) + else if (flag1 == ACTIVE_FLAG && flag2 == OBSOLETE_FLAG) { gd->env_addr = addr1; gd->env_valid = 1; } - else if (flag1 == obsolete_flag && flag2 == active_flag) + else if (flag1 == OBSOLETE_FLAG && flag2 == ACTIVE_FLAG) { gd->env_addr = addr2; gd->env_valid = 1; @@ -161,6 +161,7 @@ int saveenv(void) { char *saved_data = NULL; int rc = 1; + char flag = OBSOLETE_FLAG, new_flag = ACTIVE_FLAG; #if CFG_ENV_SECT_SIZE > CFG_ENV_SIZE ulong up_data = 0; #endif @@ -215,11 +216,11 @@ int saveenv(void) (ulong)&(flash_addr_new->crc), sizeof(env_ptr->crc)) || - flash_write((char *)&obsolete_flag, + flash_write(&flag, (ulong)&(flash_addr->flags), sizeof(flash_addr->flags)) || - flash_write((char *)&active_flag, + flash_write(&new_flag, (ulong)&(flash_addr_new->flags), sizeof(flash_addr_new->flags))) { @@ -373,24 +374,28 @@ void env_relocate_spec (void) end_addr_new = ltmp; } - if (flash_addr_new->flags != obsolete_flag && + if (flash_addr_new->flags != OBSOLETE_FLAG && crc32(0, flash_addr_new->data, ENV_SIZE) == flash_addr_new->crc) { + char flag = OBSOLETE_FLAG; + gd->env_valid = 2; flash_sect_protect (0, (ulong)flash_addr_new, end_addr_new); - flash_write((char *)&obsolete_flag, + flash_write(&flag, (ulong)&(flash_addr_new->flags), sizeof(flash_addr_new->flags)); flash_sect_protect (1, (ulong)flash_addr_new, end_addr_new); } - if (flash_addr->flags != active_flag && - (flash_addr->flags & active_flag) == active_flag) + if (flash_addr->flags != ACTIVE_FLAG && + (flash_addr->flags & ACTIVE_FLAG) == ACTIVE_FLAG) { + char flag = ACTIVE_FLAG; + gd->env_valid = 2; flash_sect_protect (0, (ulong)flash_addr, end_addr); - flash_write((char *)&active_flag, + flash_write(&flag, (ulong)&(flash_addr->flags), sizeof(flash_addr->flags)); flash_sect_protect (1, (ulong)flash_addr, end_addr);

[U-Boot-Users] PATCH: strswab
by Leon Kukovec 14 Mar '04

14 Mar '04

Hi Wolfgang, I've decided to split the PXA IDE/PCMCIA/CF patch into several smaller ones. Here's the patch that adds strswab functions and updates ide_ident() accordingly. The CROSS_COMPILE variable in Makefile you can reject if you think it's not needed. I do not have a shell environment variable CROSS_COMPILE and it turned out that dirname was barking - CROSS_COMPILE in my environment is only set in the Makefile. Fixes: o IDE firmware and model number are shown correctly on little endian machines Changes: o added strswab function which swaps adjacent odd and even bytes in a NUL-terminated string o fixed IDE LBA capacity, device firmware and model number on little endian machines Any issues, let me know. -- Best Regards, Leon.

[U-Boot-Users] patch for NFS
by Masami Komiya 14 Mar '04

14 Mar '04

I found out that we don't mind the ramdomness of RPC transaction id in U-BOOT. The attached patch removes get_ticks() from the NFS implementation. Change Log: - Remove get_ticks() of NFS code. - Add the verification of the RPC transaction id. Masami Komiya

[U-Boot-Users] Patch generalizing USB driver for MPC5200
by Reinhard Meyer 14 Mar '04

14 Mar '04

1. This spatch removes the compiler warnings (integer made from pointer without cast) 2. it generalizes the Clock Divider Values and the Port Config for USB if CONFIG_USB_CDMFDC5xxx and CONFIG_USB_GPSCFG5xxx are NOT defined, nothing changes. Defining them allows for other system clocks than 528 MHz and/or other types of USB Port Configurations, for example single ended (#define CONFIG_USB_GPSCFG5xxx 0x00005000) Thanks, Pierre, for the good work, the driver works fine on our board!

[U-Boot-Users] Patch PPC440GX speed
by Carl Riechers 14 Mar '04

14 Mar '04

This patch adds the PPC440GX prbdv0 divider to the memory clock equation. This is my first experience with u-boot, my thanks to Wolfgang, Travis, and everyone that has contributed. I saw my first u-boot prompt after adding this divider with the correct SDRAM settings.
