[U-Boot-Users] [PATCH] Altera Stratix II support
by eran liberty 26 Mar '08

26 Mar '08

Addes Support for Altera's Stratix II. Patch against commit 661bad63a076a96c39c64f136915f146725af92b A.k.a v1.3.2-rc3 can be downloaded publicly from: https://fo.extricom.com/pub/u-boot/u-boot-1.3.2-rc3_stritixII.patch Signed-off-by: Eran Liberty <liberty(a)extricom.com> Within your board specific init file you will have to call 1. fpga_init (/* relocated code offset. usually => */ gd->reloc_off); 2. fpga_add (fpga_altera, (Altera_desc*)&altera_desc); Altera_desc* contines (for example): { Altera_StratixII, /* part type */ passive_serial, /* interface type */ 1, /* bytes of data part can accept */ (void *)(&funcs), /* interface function table */ 0L, /* base interface address */ 0 /* implementation specific cookie */ } funcs is the interface. It is of type altera_board_specific_func. It looks like this: altera_board_specific_func func = { pre_fn, config_fn, status_fn, done_fn, clk_fn, data_fn, abort_fn, post_fn, }; you will have to implement these functions, which is usually bit banging some gpio. within the coming days I will submit a Patch of my own board which demonstrate all this. Have fun, Liberty

[U-Boot-Users] [PATCH v2 0/7] Respin of Sascha Hauer's i.MX31 support plus MX31ADS
by Guennadi Liakhovetski 26 Mar '08

26 Mar '08

This series of patches is a respin on the current git-top of Sascha's i.MX31 support in U-Boot with minor additions / improvements, plus support for the MX31ADS evaluation board from Freescale. Changes in v2: "C++ style comments" removed, CONFIG_FIT disabled on all three boards, patch 7/7 formatting damage fixed, fixed CONFIG_CMD_* macros.

[U-Boot-Users] Adding support for new board (jornada720 + flashrom)
by Kristoffer Ericson 26 Mar '08

26 Mar '08

Greetings, What do I need to set to get new board supported. Im using a flashrom (64MB ROM / 128MB RAM) and the hardware should be quite similiar to assabet. blob already is working, but somewhat lacking. Does u-boot create the tagged list? Best wishes Kristoffer

[U-Boot-Users] [PATCH] USB Storage, add meaningful return value
by Aras Vaichas 26 Mar '08

26 Mar '08

This patch changes the "usb storage" command to return success iff it finds a USB storage device, otherwise it returns error. This enables you to check for a USB storage device before trying to access it: if usb storage; then fatload usb 0 $loadaddr $filename; fi ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

Wolfgang, I have three outstanding patches to move a few Freescale boards from board/* to board/freescale/*. I wasn't sure if you would apply them directly or not, and didn't get any response from you when I asked. (No problem.) So I decided to make it easier for you and just placed them in my -mpc86xx tree for you to pull directly. They have been rebased to the current top of tree. If you would, please pick these up!

The reference clk and xcorevdd voltage of serdes1/2 is same between mpc837xemds and mpc837xerdb. 8377E: LYNX1- 2 SATA LYNX2- 2 PCIE 8378E: LYNX1- 2 SGMII LYNX2- 2 PCIE 8379E: LYNX1- 2 SATA LYNX2- 2 SATA Signed-off-by: Dave Liu <daveliu(a)freescale.com> --- board/freescale/mpc837xemds/mpc837xemds.c | 33 +++++++++++++++++++++++++++++ include/configs/MPC837XEMDS.h | 5 ++++ 2 files changed, 38 insertions(+), 0 deletions(-) diff --git a/board/freescale/mpc837xemds/mpc837xemds.c b/board/freescale/mpc837xemds/mpc837xemds.c index e57a53f..6fbd0e0 100644 --- a/board/freescale/mpc837xemds/mpc837xemds.c +++ b/board/freescale/mpc837xemds/mpc837xemds.c @@ -12,6 +12,8 @@ #include <common.h> #include <i2c.h> +#include <asm/io.h> +#include <asm/fsl_serdes.h> #include <spd_sdram.h> #if defined(CONFIG_OF_LIBFDT) #include <libfdt.h> @@ -29,6 +31,37 @@ int board_early_init_f(void) /* Clear all of the interrupt of BCSR */ bcsr[0xe] = 0xff; +#ifdef CONFIG_FSL_SERDES + immap_t *immr = (immap_t *)CFG_IMMR; + u32 spridr = in_be32(&immr->sysconf.spridr); + + /* we check only part num, and don't look for CPU revisions */ + switch (spridr >> 16) { + case SPR_8379E_REV10 >> 16: + case SPR_8379_REV10 >> 16: + fsl_setup_serdes(CONFIG_FSL_SERDES1, FSL_SERDES_PROTO_SATA, + FSL_SERDES_CLK_100, FSL_SERDES_VDD_1V); + fsl_setup_serdes(CONFIG_FSL_SERDES2, FSL_SERDES_PROTO_SATA, + FSL_SERDES_CLK_100, FSL_SERDES_VDD_1V); + break; + case SPR_8378E_REV10 >> 16: + case SPR_8378_REV10 >> 16: + fsl_setup_serdes(CONFIG_FSL_SERDES1, FSL_SERDES_PROTO_PEX, + FSL_SERDES_CLK_100, FSL_SERDES_VDD_1V); + break; + case SPR_8377E_REV10 >> 16: + case SPR_8377_REV10 >> 16: + fsl_setup_serdes(CONFIG_FSL_SERDES1, FSL_SERDES_PROTO_SATA, + FSL_SERDES_CLK_100, FSL_SERDES_VDD_1V); + fsl_setup_serdes(CONFIG_FSL_SERDES2, FSL_SERDES_PROTO_PEX, + FSL_SERDES_CLK_100, FSL_SERDES_VDD_1V); + break; + default: + printf("serdes not configured: unknown CPU part number: " + "%04x\n", spridr >> 16); + break; + } +#endif /* CONFIG_FSL_SERDES */ return 0; } diff --git a/include/configs/MPC837XEMDS.h b/include/configs/MPC837XEMDS.h index b307bf7..4006026 100644 --- a/include/configs/MPC837XEMDS.h +++ b/include/configs/MPC837XEMDS.h @@ -389,6 +389,11 @@ /* Options are: TSEC[0-1] */ #define CONFIG_ETHPRIME "eTSEC1" +/* SERDES */ +#define CONFIG_FSL_SERDES +#define CONFIG_FSL_SERDES1 0xe3000 +#define CONFIG_FSL_SERDES2 0xe3100 + /* * Environment */ -- 1.5.4.rc4
