>From 8bd3d40edb36a8b480aa6f2fbc0c8b3f2be5aae8 Mon Sep 17 00:00:00 2001 From: Randy Vinson <rvinson(a)linuxbox.(none)> Date: Tue, 27 Feb 2007 19:42:22 -0700 Subject: [PATCH] 85xxCDS: Add make targets for legacy systems. The PCI ID select values on the Arcadia main board differ depending on the version of the hardware. The standard configuration supports Rev 3.1. The legacy target supports Rev 2.x.

[U-Boot-Users] 85xx from git repo question
by robert lazarski 13 Aug '07

13 Aug '07

Hi all, I've noticed a difference from u-boot 1.2.0 and the Freescale 85xx git repo - particularly PEX and the mpc8548cds. Looking at the CDS schematic I believe that's PCI express. I noticed there is now a TLB entry for PEX - unlike previous versions: * 0xe300_0000 0xe3ff_ffff PEX IO 16M I asked about PCI Express for 85xx on the list recently and was informed "You do not need to specify TLB/LAW for PCI-X. it uses the same memory map as PCI1." What is the PEX TLB entry for? The mpc8548cds docs in the git repo haven't been updated yet. I have a 8548 custom board - similar somewhat to the mpc8548cds and I'm using that as a reference - that arrives right around the August 17th code freeze. I'm planning on using the git repo code for my developement rather than the stable release code of 1.2.0. Is the repo code recommended over 1.2.0 ? It probably is but I thought I'd ask. Thanks, Robert

[U-Boot-Users] Pull Request for u-boot-mpc86xx

Wolfgang, The following changes since commit 99c2fdab91bc633e46fb41dbaa629f87ccf6e00f: Kim Phillips (1): mpc83xx: fix ITX[GP] O=builddir builds are available in the git repository at: git://www.denx.de/git/u-boot-mpc86xx.git Basically, this pull will fix a few mpc86xx and mpc85xx PCI/PCI-E bugs as well as add the SBC8641D board from Joe Hamman. All of these patches have already been published on the mail list, and those that touch common files have also been ACK'ed by an independent person (pci_auto.c). I've merged in current mainline first, so this should apply cleanly after the MAKEALL changes even! Thanks, jdl Ed Swarthout (2): pciauto_setup_device bars_num fix fsl_pci_init cleanup. Joe Hamman (3): Add support for SBC8641D. Board files. Add support for SBC8641D. Config files.

[U-Boot-Users] [PATCH] MPC85xx BA bits not set for 3-bit bank address DIMM
by Greg Davis 13 Aug '07

13 Aug '07

The current implementation does not set the number of bank address bits (BA) in the processor. The default assumes 2 logical bank bits. This works fine for a DIMM that uses devices with 4 internal banks (SPD byte17 = 0x4) but needs to be set appropriately for a DIMM that uses devices with 8 internal banks (SPD byte17 = 0x8).

[U-Boot-Users] [PATCH] Fix for mcf5329evb - spurious interrupts on Linux/uClinux kernel boot
by Robert S. Grimes 13 Aug '07

13 Aug '07

Hi TsiChung, I followed your most recent advice, and it works like a charm! Thanks! Attached is a very small patch that implements the fix - when CONFIG_MCF532x is defined, the timer interrupt is masked immediately prior to calling into the kernel. I don't know if this is the right way to submit patches, but I assume you'll take over from here, right? Aaron, Wolfgang: I sent this directly to you in case you're interested... Take care, -Bob P.S. Aaron, you were right - I do indeed have 32 MBytes... Thanks!
