Hello, I'm sorry, but I cannot issue -rc1 today as I had planned because I'm still waiting for pull requests from some custodians. I think I will put out -rc1 Sunday night or Monday at latest, no matter that stuff is available then or not. Note that I intend to accept only bug fixes then, i. e. no new features will go into the master branch then. We will have a next branch, though.

[U-Boot] [PATCH v4] ppc4xx: Add GDsys CompactCenter board support.
by Dirk Eibach 24 Jul '09

24 Jul '09

Board support for the Guntermann & Drunck CompactCenter and DevCon-Center. Based on the AMCC Canyonlands board support by Stefan Roese. Signed-off-by: Dirk Eibach <eibach(a)gdsys.de> --- Changes since v1: - removed dead code - whitespace cleanup - simplified code for nand/nor distinction in board/gdsys/compactcenter/bootstra p.c Changes since v2: - removed get_cpu_num() from board/gdsys/compactcenter/compactcenter.c - use __ft_board_setup() instead of ft_cpu_setup() - cleanup CompactCenter/Canyonlands mixup - reformatted CONFIG_SYS_4xx_GPIO_TABLE. Lines are > 80 chars but readable. Changes since v3: - took nor fixup from canyonlands (This still depends on __ft_board_setup() working properly, which is not the case yet) - use chip_config instead of bootstrap command MAINTAINERS | 2 + MAKEALL | 2 + Makefile | 8 + board/gdsys/compactcenter/Makefile | 53 ++++ board/gdsys/compactcenter/chip_config.c | 87 ++++++ board/gdsys/compactcenter/compactcenter.c | 312 ++++++++++++++++++++ board/gdsys/compactcenter/config.mk | 41 +++ board/gdsys/compactcenter/init.S | 97 +++++++ board/gdsys/compactcenter/u-boot.lds | 144 ++++++++++ include/configs/compactcenter.h | 437 +++++++++++++++++++++++++++++ 10 files changed, 1183 insertions(+), 0 deletions(-) create mode 100644 board/gdsys/compactcenter/Makefile create mode 100644 board/gdsys/compactcenter/chip_config.c create mode 100644 board/gdsys/compactcenter/compactcenter.c create mode 100644 board/gdsys/compactcenter/config.mk create mode 100644 board/gdsys/compactcenter/init.S create mode 100644 board/gdsys/compactcenter/u-boot.lds create mode 100644 include/configs/compactcenter.h diff --git a/MAINTAINERS b/MAINTAINERS index 575a7ec..888eb5c 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -135,6 +135,8 @@ Jon Diekema <jon.diekema(a)smiths-aerospace.com> Dirk Eibach <eibach(a)gdsys.de> + compactcenter PPC460EX + devconcenter PPC460EX gdppc440etx PPC440EP/GR neo PPC405EP diff --git a/MAKEALL b/MAKEALL index 020ff73..7359b2e 100755 --- a/MAKEALL +++ b/MAKEALL @@ -184,6 +184,7 @@ LIST_4xx=" \ canyonlands \ canyonlands_nand \ CMS700 \ + compactcenter \ CPCI2DP \ CPCI405 \ CPCI4052 \ @@ -194,6 +195,7 @@ LIST_4xx=" \ csb272 \ csb472 \ DASA_SIM \ + devconcenter \ DP405 \ DU405 \ DU440 \ diff --git a/Makefile b/Makefile index 090e645..9be17f6 100644 --- a/Makefile +++ b/Makefile @@ -1308,6 +1308,14 @@ CATcenter_33_config: unconfig CMS700_config: unconfig @$(MKCONFIG) $(@:_config=) ppc ppc4xx cms700 esd +# Compact-Center & DevCon-Center use different U-Boot images +compactcenter_config \ +devconcenter_config: unconfig + @mkdir -p $(obj)include + @echo "#define CONFIG_$$(echo $(subst ,,$(@:_config=)) | \ + tr '[:lower:]' '[:upper:]')" >$(obj)include/config.h + @$(MKCONFIG) -n $@ -a compactcenter ppc ppc4xx compactcenter gdsys + CPCI2DP_config: unconfig @$(MKCONFIG) $(@:_config=) ppc ppc4xx cpci2dp esd diff --git a/board/gdsys/compactcenter/Makefile b/board/gdsys/compactcenter/Makefile new file mode 100644 index 0000000..12f8a64 --- /dev/null +++ b/board/gdsys/compactcenter/Makefile @@ -0,0 +1,53 @@ +# +# (C) Copyright 2008 +# Stefan Roese, DENX Software Engineering, sr(a)denx.de. +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[U-Boot] PPC440GX TLB setting problem.
by Wouter Eckhardt 24 Jul '09

24 Jul '09

Hi all, I'm working on trying to get VxWorks to boot on a PPC440GX processor using U-Boot, using an ALPR board. In order to boot VxWorks properly (it expects caching on the SDRAM to be disabled), I created a new board directory and such (based on the ALPR board), and then changed the TLB settings in init.S. My problem is that when my new U-Boot has booted, the TLBs are not configured as I have programmed them. I verified this using a BDI debugger. The TLB settings are still the same as the settings the original ALPR U-Boot used. I'm really at a loss here. It seems that no matter what I try (I tried quite a few variantions of the TLB settings), the TLB settings won't change. So now I several, related, questions: - What could be the cause of this? Have I done something wrong? - Is U-Boot reconfiguring the TLBs after init.S has executed? - If so, how can I control those TLBs? Here's a code snippet from my init.S: /*********************************************************************** *** * TLB TABLE * * This table is used by the cpu boot code to setup the initial tlb * entries. Rather than make broad assumptions in the cpu source tree, * this table lets each board set things up however they like. * * Pointer to the table is returned in r1 * ************************************************************************ */ /* Updated to reflect TLB entries in VxWorks. */ .section .bootpg,"ax" .globl tlbtab tlbtab: tlbtab_start tlbentry( CFG_SDRAM_BASE, SZ_256M, 0x00000000, 0, AC_R|AC_W|AC_X|SA_G|SA_I ) tlbentry( 0x80000000, SZ_256M, 0x00000000, 0, AC_R|AC_W|AC_X|SA_I ) tlbentry( CFG_PERIPHERAL_BASE, SZ_256M, 0x40000000, 1, AC_R|AC_W|SA_G|SA_I ) tlbentry( 0xf0000000, SZ_256M, 0xf0000000, 1, AC_R|AC_W|AC_X|SA_G|SA_I ) tlbentry( CFG_ISRAM_BASE, SZ_256K, 0x80000000, 0, AC_R|AC_W|AC_X ) #ifdef CFG_INIT_RAM_DCACHE /* TLB-entry for init-ram in dcache (SA_I must be turned off!) */ tlbentry( CFG_INIT_RAM_ADDR, SZ_64K, CFG_INIT_RAM_ADDR, 0, AC_R|AC_W|AC_X|SA_G ) #endif tlbtab_end And here's the BDI's listing of the TLBs after U-Boot has booted (no auto boot): - TARGET: processing target startup .... - TARGET: processing target startup passed ALPR>go ALPR>halt Core number : 0 Core state : debug mode Debug entry cause : JTAG stop request Current PC : 0x0ffe372c Current CR : 0x28dcff82 Current MSR : 0x00029000 Current LR : 0x0ffe378c ALPR>tlb 0 15 IDX TID EPN SIZE VTS RPN USER WIMGE USRSVC 0 : 00 ff000000 16MB V0 -> 1_ff000000 U:0000 -I-G- XWRXWR 1 : 00 e0000000 256MB V0 -> 1_40000000 U:0000 -I-G- -WR-WR 2 : 00 c0000000 4KB V0 -> 0_80000000 U:0000 ----- XWRXWR 3 : 00 c0001000 4KB V0 -> 0_80001000 U:0000 ----- XWRXWR 4 : 00 00000000 256MB V0 -> 0_00000000 U:0000 ---G- XWRXWR 5 : 00 d0000000 256MB V0 -> 2_00000000 U:0000 -I-G- -WR-WR 6 : 00 80000000 256MB V0 -> 3_80000000 U:0000 -I-G- -WR-WR 7 : 00 90000000 256MB V0 -> 3_90000000 U:0000 -I-G- -WR-WR 8 : 00 a0000000 256MB V0 -> 3_a0000000 U:0000 -I-G- -WR-WR 9 : 00 f0000000 4KB V0 -> 1_f0000000 U:0000 -I-G- XWRXWR 10 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ 11 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ 12 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ 13 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ 14 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ 15 : 00 00000000 1KB -0 -> 0_00000000 U:0000 ----- ------ ALPR> Thanks in advance!

[U-Boot] [PATCH] ppc4xx: Fix TLB reset problem with recent 44x images
by Stefan Roese 24 Jul '09

24 Jul '09

Patch d873133f [ppc4xx: Add Sequoia RAM-booting target] broke "normal" booting on some 44x platforms. This breakage is only noticed in some cases while powercycling. As it seems, the code in question in start.S didn't invalidate TLB #0. This makes sense since this TLB is used for the bootrom mapping. With the patch mentioned above even TLB #0 got invalidated resulting in an error later on. This patch now fixes this issue by only invalidating TLB #0 in the RAM- booting case. Tested succesfully on Sequoia and Canyonlands.

[U-Boot] [PATCH v2] ppc4xx: Fix EEPROM configuration on Kilauea
by Stefan Roese 24 Jul '09

24 Jul '09

Kilauea has an AT24C02 EEPROM which has an 8 byte page. Without defining CONFIG_SYS_EEPROM_PAGE_WRITE_BITS to 3 the "eeprom" command doesn't work correctly. Additionally the page write delay (CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS) is set to a more defensive value of 10ms.

[U-Boot] [PATCH v6] Add "chip_config" command for PPC4xx bootstrap configuration
by Stefan Roese 24 Jul '09

24 Jul '09

This patch adds a generic command for programming I2C bootstrap eeproms on PPC4xx. An implementation for Canyonlands board is included. The command name is intentionally chosen not to be PPC4xx specific. This way other CPU's/SoC's can implement a similar command under the same name, perhaps with a different syntax. Usage on Canyonlands: => chip_config Available configurations (I2C address 0x52): 600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100 600-nand - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100 800-nor - NOR CPU: 800 PLB: 200 OPB: 100 EBC: 100 800-nand - NAND CPU: 800 PLB: 200 OPB: 100 EBC: 100 1000-nor - NOR CPU:1000 PLB: 200 OPB: 100 EBC: 100 1000-nand - NAND CPU:1000 PLB: 200 OPB: 100 EBC: 100 1066-nor - NOR CPU:1066 PLB: 266 OPB: 88 EBC: 88 *** 1066-nand - NAND CPU:1066 PLB: 266 OPB: 88 EBC: 88 => chip_config 600-nor Using configuration: 600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100 done (dump via 'i2c md 52 0.1 10') Reset the board for the changes to take effect Other 4xx boards will be migrated to use this command soon as well.

[U-Boot] [PATCH 1/2] ppc4xx: use TCR macro instead of tcr
by matthias.fuchs＠esd.eu 24 Jul '09

24 Jul '09

From: Matthias Fuchs <matthias.fuchs(a)esd.eu> This patch migrates 4xx code from using the lowercase tcr macro to the uppercase TCR macro. Both macros have been defined in the past. So one is to much and uppercase macros are much more common. The lowercase macro conflicts with the upcoming introduction of the ppc4xx_gpio struct and it's tcr field.
