Re: [U-Boot-Users] U-boot ColdFire development

Stefan, I made some update on the 5329. We need to get started on migrating the mcf52x2 as soon as possible. 1. Files that use <asm/immap_5329.h> and <asm/m5329.h> were replaced to <asm/immap.h>. 2. CPU/ARCH specific defines are placed in include/asm/immap.h 3. drivers/serial/mcfserial.c renamed to drivers/serial/mcfuart.c. I want to keep it that way so that it won't mix up with other uarts drivers. 4. rtc/rtc.c renamed to rtc/mcfrtc.c, same reason as no. 3 5. cache_enable() moved from cpu_init_r() to cpu_init_f() for fast allocation 6. used generic cfi driver 7. Will keep the cpu folder for each family. Certain CPU has different cache and speed configuration. 8. MII will still be placed in board/xxxx/mii.c http://opensource.freescale.com/git?p=u-boot-coldfire.git;a=summary Regards, TsiChung -----Original Message----- From: Liew Tsi Chung-r5aahp Sent: Thursday, June 21, 2007 8:53 AM To: Stefan Roese Cc: Wolfgang Denk; u-boot-users(a)lists.sourceforge.net Subject: RE: U-boot ColdFire development Stefan, Here is the test version for 5329 u-boot source at Freescale. http://opensource.freescale.com/git?p=u-boot-coldfire.git;a=summary Added: board/freescale/M5329EVB/Makefile config.mk flash.c m5329evb.c and u-boot.lds cpu/mcf532x/Makefile config.mk cpu.c cpu_init.c speed.c start.S drivers/net/mcffec.c drivers/serial/mcfserial.c include/asm-m68k/immap_5329.h m5329.h mcfrtc.h include/configs/M5329EVB.h lib_m68k/interrupts.c rtc/rtc.c Modified: Makefile MAKEALL README common/cmd_bdinfo.c cmd_mii.c include/asm-m68k/byteorder.h fec.h io.h mcftimer.h mcfuart.h ptrace.h u-boot.h lib_m68k/board.c time.c I had placed the mcfserial.c under drivers/serial and mcffec.c under drivers/net. The rtc.c is under rtc/. 1. I do have one more doubt about placing the following defines as we discussed early. > /* Timer */ > #define CONFIG_MCFTMR > #ifdef CONFIG_MCFTMR > # define CFG_UDELAY_BASE (0xFC070000) > # define CFG_TMR_BASE (0xFC074000) > # define CFG_INTR_BASE (0xFC048000) > # define CFG_TMRINTR_NO (32) > # define CFG_TMRINTR_MASK (1) > #endif If I place the #ifdef CONFIG_MCFTMR ... #endif in say immap_5329.h, isn't that in time.c must include <asm/immap_5329.h>. Time.c #ifdef CONFIG_5329 #include <asm/immap_5329.h> #endif #ifdef CONFIG_5272 #include <asm/immap_5272.h> #endif ... Is there a way not to include <asm/immap_5xxx.h> in time.c each time a new processor is added? 2. I seperated the MII feature from fec.c and placed in under board/freescale/mxxxevb.c. Since the mii phy is board dependent not cpu dependent, do you agree? 3. EHCI/OTG driver development. Do I need to modify the current cmd_usb.c to include EHCI or create a new file cmd_hsusb.c? Regards, TsiChung

A few things: 1. Please don't e-mail me without including the U-boot list unless it's something only I would be interested in, such as cheap Cialis or maybe the chance to help recover millions of dollars from the widow of Saddam Hussein's cousin-in-law. 2. Please don't top post. That out of the way... This tool isn't built by default. I've attached a couple of patches that apply cleanly to the latest git tree: - The first turns on building of the tool. - The second fixes compile errors and warnings that I came across a few months ago. I expect you'll need it if you're using Linux 2.6. If you're using a 2.4 kernel, I don't know if this is needed or not. regards, Ben

[U-Boot-Users] ELDK and newer kernels
by robert lazarski 27 Jul '07

27 Jul '07

Hi all, sorry if this question is inappropriate for this list. I'm developing for the MPC8548E and in 2.6.20 there was drivers/ata/pata_marvell.c merged, which I need for a Marvell 88SE6121. I noticed eldk comes with a kernel, kernel-source-2.6.19.2-1.noarch.rpm . I'd like to use the ELDK kernel with the MPC8548E for my custom board , using the CDS board for my reference. Is there any feel for a new 2.6.20 or later ELDK kernel that'll run the MPC8548CDS within the next month or two? Robert

[U-Boot-Users] [PATCH 1/8] Add PPC4xx-HCU4 and HCU5 boards: Infrastructure
by Niklaus Giger 27 Jul '07

27 Jul '07

This series of patches adds support for 2 boards from Netstal Maschinen. The HCU4 has a PPC405Gpr and the HCU5 has a PPC440EPX. The HCU4 has a somehow complicated flash setup, as the booteprom is only 8 bits and the CFI 16 bits wide, which makes it impossible to use a more elegant solution. The HCU5 has only a booteprom as the whole code will be downloaded from a different board which has HD, CD-ROM, etc and where all code is stored. This is my third try. I incorporated all suggestions made by Wolfgang and Stefan. Thanks them a lot.
