[U-Boot-Users] [PATCH] MPC5200: Check SVR in checkcpu ()
by Mark Jonas 09 Jun '04

09 Jun '04

Hello, attached you'll find a patch to check the SVR (System Version Register) of MPC5200 to determine the silicon version of the chip and to identify the chip itself. This patch applies to all boards using the checkcpu () function in cpu/mpc5xxx/cpu.c. Regards Mark * Patch by Mark Jonas, 08 June 2004: - MPC5200 boards now evaluate the SVR to print processor name and version in checkcpu() (cpu/mpc5xxx/cpu.c). cpu/mpc5xxx/cpu.c | 19 ++++++++++++++++++- cpu/mpc5xxx/start.S | 5 +++++ include/asm-ppc/processor.h | 19 +++++++++++++++++++ include/common.h | 3 +++ 4 files changed, 45 insertions(+), 1 deletion(-)

[U-Boot-Users] [Patch] for MPC8540ADS and MPC8560ADS boards
by Jon Loeliger 09 Jun '04

09 Jun '04

Wolfgang, Here are some patches for the MPC 8540/8560 ADS boards. Since I believe others have already applied my previous patches from 11-May-2004 for these two boards, this is an incremental patch and assumes that those previous patches have already been applied. A CHANGELOG follows. Thanks, jdl * Patch by Jon Loeliger, 1-Jun-2004 All these are on the MPC 8540/8560 ADS boards: Fix SDRAM initialization Documented BR2 and OR2 (SDRAM) registers. Fix and enable PCI bus by default. Added Rapid IO memory mappings. Fixes for the CFG_INIT_DBCR option. Some README.MPC85xxads updates. Better documentation for PCI 33/66 switches. Whitespace cleanup for consistency.

RE: [U-Boot-Users] [PATCH] OMAP1610 cs boot mode
by Imre.Deak＠nokia.com 09 Jun '04

09 Jun '04

Hi Wolfgang, Sorry if the name is misleading, or not exact, I tried to denote with it the following: In order to set the correct base address for the flash memory, U-Boot has to know somehow the boot mode of the board. There are two of it. In the first ROM is mapped to address 0 and the flash is to address 0x0C00000. In the second mode the two are swapped, ROM is at 0x0C000000 and flash is at 0. Boot happens always from address 0. In this way we can effectivly select (with a dip switch) where we'd like to boot from. At the moment U-Boot has to be configured to either of the two modes. There are 3 make targets for this, first and third being equivalent: omap1610h2_config ( ==omap1610h2_cs3_boot_config ) omap1610h2_cs0_boot_config omap1610h2_cs3_boot_config It is possible however to determine the boot mode automatically, from an OMAP status register and thus set the flash base address correctly. For this I added a new target omap1610h2_cs_autoboot_config. Maybe it should be a CONFIG variable instead of 4 targets for each board (H2, Innovator), like CONFIG_OMAP_BOOTMODE_CS0 CONFIG_OMAP_BOOTMODE_CS3 CONFIG_OMAP_BOOTMODE_DETECT ?

I accidentally sent you a patch update that contained reverse deltas for the updates that you performed between those two dates. My apologies. jdl

[U-Boot-Users] Fix for MPC5xxx i2c timing issue
by Martin Krause 09 Jun '04

09 Jun '04

Hello, this patch fixes a timing problem in the MPC5xxx I2C function i2c_probe(). The problem could occour, if i2c_probe() is called successive without delay between the calls as for example in I2C POST test. On my board the POST test found a second I2C EEPROM device that doesn't really exist right after the real EEPROM. The patch fixed this problem. * Patch by Martin Krause, 27 May 2004: Fix a MPC5xxx I2C timing issue in i2c_probe().
