[U-Boot] [PATCH v2 1/3] Add Eukrea CPUIMX27 support
by Eric Benard 03 Aug '09

03 Aug '09

CPUIMX27 is built around Freescale's i.MX27 and has up to 64MB of NOR Flash, up to 512MB of NAND Flash and up to 256MB of mDDR, it includes an ethernet PHY in MII mode, an I2C RTC and a ST16554 QuadUART on nCS3.

[U-Boot] Changing serial port and sending arbitrary data over serial interface
by Matthias Weisser 03 Aug '09

03 Aug '09

Hi I am currently in the process of reworking my patches to bring my u-boot port into the official git. All my work is based on latest head. Now I came to a point where I don't know how to do it and also didn't find any board doing the same thing. My system has six NS16550 serial ports where u-boot only needs to deal with three of them. So I defined: #define CONFIG_SYS_NS16550 #define CONFIG_SYS_NS16550_SERIAL #define CONFIG_SYS_NS16550_REG_SIZE (-4) #define CONFIG_SYS_NS16550_CLK CONFIG_JADE_IOCLK #define CONFIG_SYS_NS16550_COM1 0xfffe1000 /* UART 0 */ #define CONFIG_SYS_NS16550_COM2 0xfffe2000 /* UART 1 */ #define CONFIG_SYS_NS16550_COM3 0xfff50000 /* UART 2 (SP) */ #define CONFIG_CONS_INDEX 1 The default is that u-boot uses COM1. Under some circumstances COM2 has to be used. So the question is: How to switch (dynamically) between the console input/output? I also have to send some arbitrary data to COM3 depending on some environment variables. These are commands to a small processor on the same board which will then switches some devices on which I need for further booting.

[U-Boot] [patch] rm9200 lowevel_init: don't touch reserved/readonly registers
by David Brownell 03 Aug '09

03 Aug '09

For some reason the AT91rm9200 lowlevel init writes to a bunch of reserved or read-only addresses. All the boards seem to define the value-to-be-written values as zero ... but they shouldn't actually be writing *anything* there. No documented erratum justifies these accesses. It looks like maybe some pre-release BDI-2000 setup code has been carried along by cargo cult programming since at least late 2004 (per GIT history). Here's a patch disabling what seems to be bogosity. Tested on a csb337; there were no behavioral changes. --- cpu/arm920t/at91rm9200/lowlevel_init.S | 14 ++------------ include/configs/at91rm9200dk.h | 5 ----- include/configs/at91rm9200ek.h | 5 ----- include/configs/cmc_pu2.h | 5 ----- include/configs/csb637.h | 5 ----- include/configs/m501sk.h | 5 ----- include/configs/mp2usb.h | 5 ----- 7 files changed, 2 insertions(+), 42 deletions(-) --- a/cpu/arm920t/at91rm9200/lowlevel_init.S +++ b/cpu/arm920t/at91rm9200/lowlevel_init.S @@ -81,6 +81,7 @@ LoopOsc: bne 0b /* delay - this is all done by guess */ ldr r0, =0x00010000 + /* (vs reading PMC_SR for LOCKA, LOCKB ... or MOSCS earlier) */ 1: subs r0, r0, #1 bhi 1b @@ -108,16 +109,6 @@ LoopOsc: .ltorg SMRDATA: - .word AT91C_MC_PUIA - .word CONFIG_SYS_MC_PUIA_VAL - .word AT91C_MC_PUP - .word CONFIG_SYS_MC_PUP_VAL - .word AT91C_MC_PUER - .word CONFIG_SYS_MC_PUER_VAL - .word AT91C_MC_ASR - .word CONFIG_SYS_MC_ASR_VAL - .word AT91C_MC_AASR - .word CONFIG_SYS_MC_AASR_VAL .word AT91C_EBI_CFGR .word CONFIG_SYS_EBI_CFGR_VAL .word AT91C_SMC_CSR0 @@ -128,8 +119,7 @@ SMRDATA: .word CONFIG_SYS_PLLBR_VAL .word AT91C_MCKR .word CONFIG_SYS_MCKR_VAL - /* SMRDATA is 80 bytes long */ - /* here there's a delay of 100 */ + /* here there's a delay */ SMRDATA1: .word AT91C_PIOC_ASR .word CONFIG_SYS_PIOC_ASR_VAL --- a/include/configs/at91rm9200dk.h +++ b/include/configs/at91rm9200dk.h @@ -45,11 +45,6 @@ #ifndef CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x00003284 /* 16bit, 2 TDF, 4 WS */ --- a/include/configs/at91rm9200ek.h +++ b/include/configs/at91rm9200ek.h @@ -56,11 +56,6 @@ #ifndef CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x00003284 /* 16bit, 2 TDF, 4 WS */ --- a/include/configs/cmc_pu2.h +++ b/include/configs/cmc_pu2.h @@ -44,11 +44,6 @@ #ifndef CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x100032ad /* 16bit, 2 TDF, 4 WS */ --- a/include/configs/csb637.h +++ b/include/configs/csb637.h @@ -45,11 +45,6 @@ #ifndef CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x00003284 /* 16bit, 2 TDF, 4 WS */ --- a/include/configs/m501sk.h +++ b/include/configs/m501sk.h @@ -46,11 +46,6 @@ */ #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x00003284 /* 16bit, 2 TDF, 4 WS */ --- a/include/configs/mp2usb.h +++ b/include/configs/mp2usb.h @@ -49,11 +49,6 @@ #ifndef CONFIG_SKIP_LOWLEVEL_INIT #define CONFIG_SYS_USE_MAIN_OSCILLATOR 1 /* flash */ -#define CONFIG_SYS_MC_PUIA_VAL 0x00000000 -#define CONFIG_SYS_MC_PUP_VAL 0x00000000 -#define CONFIG_SYS_MC_PUER_VAL 0x00000000 -#define CONFIG_SYS_MC_ASR_VAL 0x00000000 -#define CONFIG_SYS_MC_AASR_VAL 0x00000000 #define CONFIG_SYS_EBI_CFGR_VAL 0x00000000 #define CONFIG_SYS_SMC_CSR0_VAL 0x00003084 /* 16bit, 2 TDF, 4 WS */

[U-Boot] Compilation error - MPC8536DS
by Felix Radensky 03 Aug '09

03 Aug '09

Hi, I'm hitting the error below when compiling the latest git u-boot for MPC8536DS target. I'm using toolchain from Freescale BSP for this board. ld version is 2.18.50.20080215, gcc version is 4.3.2. Any ideas how to fix this ?

Dear Jean-Christophe, can you please update me on the status of the ARM repository, and provide some forecast when you will send a pull request? The merge window was closed two weeks ago, and still I have not seen a pull request for ARM! Please understand this is becoming really urgent now. If you need help please let us know.

[U-Boot] [STATUS] Mailing list digest settings changed
by Wolfgang Denk 02 Aug '09

02 Aug '09

Hi all, I want to inform you about a change in the configuration of the mailing list software. I received complaints that multiple (up to 15) digest e-mails were sent per day. This was most probably caused by the fact that the default mailman settings had a digest size thresh- hold of only 30 KB. I changed this now to 512 KB. Please let me know if this change should cause problems to anybody. Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de I am an atheist, thank God!

[U-Boot] Missing __udivdi3 for ARM
by J.C. Wren 02 Aug '09

02 Aug '09

I enabled CONFIG_YAFFS2 for ARM, and got the following message: /home/user/u-boot/fs/yaffs2/yaffscfg.c:185: undefined reference to `__udivdi3' I know some other math routines have been fixed, is there a patch for this one? A few minutes of searching found some things from 2007-July, but it seemed to be refactoring the code rather than adding the function. Thanks, --jc

Fix a typo in the GCDR(x) macro. It's a good thing no one was using it.
