[U-Boot] [RFC] ARM: Toolchain configuration for Cortex A8 based OMAP3?
by Dirk Behme 28 Aug '08

28 Aug '08

While preparing U-Boot patches for ARM Cortex A8 based OMAP3 [1], we found that we use CodeSourcery ARM toolchain [2], and the way we locally modified main Makefile to use this toolchain is most probably incompatible with mainline. Please find below some diffs what we did locally. We now like to discuss/ask what's the best way to align this with mainline to be able to submit OMAP3 patches? Any hints or proposals? Many thanks, Dirk [1] http://www.sakoman.net/cgi-bin/gitweb.cgi?p=u-boot-omap3.git;a=summary ('common' branch) [2] http://www.codesourcery.com/gnu_toolchains/arm/portal/release313 Relevant parts of OMAP3 patch we talk about here (most probably reformated cause of copy & paste to mailtool, so just for discussion. Final patches will be sent by git-send-mail).

[U-Boot] Need Info regarding global label memsetup & file memsetup.s
by Gururaja Hebbar K R 28 Aug '08

28 Aug '08

Hi, I was going through ARM integrator[cp/ap] (u-boot-1.3.3) board files & found occurrences of memsetup global variables & file memsetup.s But according to a changelog entry, memsetup global label is changed/merged to lowlevel_init & memsetup.s is changed/merged to lowlevel_init.S. Below are the memsetup entries inside integrator[cp/ap] directories. I was unable to find a call to memsetup global entry anywhere in whole of u-boot-1.3.3 directory 1. uboot-1.3.3\board\integrator[cp/ap]\memsetup.S Redundant file. This file should be removed. File content: /* GPL ..snip.. ..snip.. Disclosure*/ /* * Memory setup * - the reset defaults are assumed sufficient */ .globl memsetup memsetup: mov pc,lr 2. Also memsetup.s entry in makefile (uboot-1.3.3\board\integrator[cp/ap]\Makefile) Once 1 step is done, this entry becomes invalid. So it needs to be removed. If i am correct, i can send a patch for the same. Please correct me if i am wrong. TIA Regards Gururaja

[U-Boot] integratorcp board - multiple definition of `__udivsi3' & undefined reference to `raise' Error
by Gururaja Hebbar K R 28 Aug '08

28 Aug '08

Hi, I am using CodeSourcery Arm Toolchain to compile U-boot-1.3.3 for integrator cp board. 1.

[U-Boot] Makeflie cleanup and u-boot size reduction
by Jean-Christophe PLAGNIOL-VILLARD 28 Aug '08

28 Aug '08

Hi, 1)The following patchset will continue the move of conditional compile to Makefile and do some file location move 2) It will merge the current list implementation for common/device & co to linux list.h in order to reduce u-boot size. During test It did show the the patch will reduce u-boot size by 1KB min. Best Regards, J.

[U-Boot] [PATCH v2 0/6] i.MX31: Add NAND support and new PDK board.
by Magnus Lilja 28 Aug '08

28 Aug '08

Hi again This series of patches adds support for the NAND flash controller in the i.MX31 device and also introduces the Freescale i.MX31 PDK board. Changes since v1: - Moved PDK board to boards/freescale/mx31pdk - Moved mxc_nd.c to driver/mtd/nand/mx31_nand.c - Moved contents of mxc_nd.h to mx31-regs.h - Cleaned up the mx31pdk.h config file after comments from this list - CONFIG_CMD_IMLS is still #undef'd but a comment is added in the config file about that. - A new patch has been inserted into the series, it makes the MC13783 SPI bus and chip select configurable. The patches are based on the current main U-boot git repo. Original intro for this series of patches: At the moment, the patch series does not add support for booting from NAND. This means that the PDK board support assumes that some other entity configures the SDRAM and loads U-boot into RAM (e.g. another bootloader or a JTAG debugger). Support for NAND boot is in progress and will be submitted later. The NAND driver is based on Freescale's Linux driver from their BSP. I've cleaned it up a bit and made the (minor) modifications necessary for U-boot. Perhaps the driver should be cleaned up even more, there are some CONFIG_MTD_MXC_* leftovers in the driver. I have tested the driver on the Litekit (small page NAND) and on the PDK (large page NAND) by having the U-boot environment placed in NAND. Regards, Magnus

[U-Boot] [PATCH] at91rm9200dk mach-type
by Claudio Scordino 28 Aug '08

28 Aug '08

Hi all, I didn't receive any feedback about this, maybe because the "PATCH" name was missing from the subject... In my opinion, it's quite strange that a file in board/atmel/at91rm9200dk sets gd->bd->bi_arch_number to MACH_TYPE_AT91RM9200 instead of MACH_TYPE_AT91RM9200DK. And, in fact, on my at91rm9200dk board U-Boot cannot boot newer versions of Linux, where the default mach type for at91rm9200 boards has been removed (see commit number 87fee013a23ad02821699aef5b76891b42959182 on Linux). The patch in attachment makes U-Boot do its job, so it should be the right fix. But I wouldn't be surprised if I made a mistake, so please, tell me if this patch is the right fix to the problem. If so, please commit it to the U-Boot git repository (it's already in git "format"). Many thanks, Claudio -- Ing.

[U-Boot] debugging u-boot relocating to ram
by Vishwanath Patil 28 Aug '08

28 Aug '08

Hello, I have a board with MPC852T, SDRAM and FLASH. I have been successful to get the console up and debug the FLASH and SDRAM connections. Now the SDRAM passes all the memory tests in SLOW mode also. The current problem I am facing is that relocate_code is being called from the lib_ppc/board.c and after that there a no messages. I want to debug the relocate code which is written in assembly language. Please help. I want to write something on portA data register to monitor the progress, in the assembly code. I am looking for a small snippet of assembly code that can write to portA register, to be put in the assembly code of the relocate_code. If someone could guide me to access the IMMR and the portA registers using the assembly language, it will be very helpful with regards Vishwanath Patil
