07 Mar '11

From: Dipen Dudhat <Dipen.Dudhat(a)freescale.com> The Integrated Flash Controller (IFC) is used to access the external NAND Flash, NOR Flash, EPROM, SRAM and Generic ASIC memories.Four chip selects are provided in IFC so that maximum of four Flash devices can be hooked, but only one can be accessed at a given time. Features supported by IFC are, - Functional muxing of pins between NAND, NOR and GPCM - Support memory banks of size 64KByte to 4 GBytes - Write protection capability (only for NAND and NOR) - Provision of Software Reset - Flexible Timing programmability for every chip select - NAND Machine - x8/ x16 NAND Flash Interface - SLC and MLC NAND Flash devices support with configurable page sizes of upto 4KB - Internal SRAM of 9KB which is directly mapped and availble at boot time for NAND Boot - Configurable block size - Boot chip select (CS0) available at system reset - NOR Machine - Data bus width of 8/16/32 - Compatible with asynchronous NOR Flash - Directly memory mapped - Supports address data multiplexed (ADM) NOR device - Boot chip select (CS0) available at system reset - GPCM Machine (NORMAL GPCM Mode) - Support for x8/16/32 bit device - Compatible with general purpose addressable device e.g. SRAM, ROM - External clock is supported with programmable division ratio - GPCM Machine (Generic ASIC Mode) - Support for x8/16/32 bit device - Address and Data are shared on I/O bus - Following Address and Data sequences can be supported on I/O bus - 32 bit I/O: AD - 16 bit I/O: AADD - 8 bit I/O : AAAADDDD - Configurable Even/Odd Parity on Address/Data bus supported Signed-off-by: Dipen Dudhat <Dipen.Dudhat(a)freescale.com> Acked-by: Scott Wood <scottwood(a)freescale.com> Signed-off-by: Kumar Gala <galak(a)kernel.crashing.org> --- Made the following fixes: Removed bugs in IFC controller header file, - Pages Per Block field has wrong mask value - TWHRE field in Timing register for NAND has wrong shift value - Corrected wrong offsets in ifc nand and nor structure map Additions to the header file are, - Added CSEL register for NAND Flash Machine - Added 36-bit Base Addreess conversion support for CSPR arch/powerpc/cpu/mpc85xx/cpu.c | 7 +- arch/powerpc/cpu/mpc8xxx/Makefile | 1 + arch/powerpc/cpu/mpc8xxx/fsl_ifc.c | 84 +++ arch/powerpc/include/asm/config.h | 2 +

[U-Boot] beagle bootcmd not working
by Egon Boormans 05 Mar '11

05 Mar '11

Dear u-boot specialists, I've been working a while now with a beagle Xm board and using u-boot to boot a linux kernel. Recently I've performed an update to version u-boot-2011.03-rc1 and found that it's not booting anymore. It looks like the bootcmd doesn't get set to the CONFIG_BOOTCOMMAND value in the 'include/configs/omap3_beagle.h' file. This value makes it into the 'include/autoconf.mk' file but not into the printenv of the u-boot. If I change the value of bootcmd (using setenv) to the CONFIG_BOOTCOMMAND value, and run bootcmd, everything works fine. Is this issue known already and if so will it be solved in the next release? Your help is appreciated. Thanks, Egon.

Good Day I am Mr. Issa Mohammed, manager in charge of audit and account section of Bank international bicia-b, Ouagadougou branch, here in Burkina Faso. I have an obscured business suggestion for you. I am here-by seeking your service in helping me receive a large amount of money and in giving a clear research and feasibility studies on areas i could invest on. Your services will be compensated with 50% of the amount you are receiving, and you will be a Partner, if your recommendation is accepted. As a bank employee, I cannot operate any personal investment till i am retired and with the Anti-corruption Bill passed in Burkina Faso; it is risky for a fixed income earner to own any huge amount of money in Burkina Faso or any foreign country. It is then advisable to invest in any foreign land secretly and patiently wait retirement. Contact me immediately for further confidential correspondence through My dearest regards Issa Mohammed

[U-Boot] multiple serial
by Ran Shalit 05 Mar '11

Hello, I am trying to undertsnad the multiple serial configuration/usage in u-boot. in doc<http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=tree;f=doc;hb=42d44f63…>/ README.serial_multi<http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob_plain;f=doc/READM…> it is said: " * 1* The support for multiple serial interfaces as implemented is mainly 2<http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=doc/README.seri…>intended to allow for modem dial-in / dial-out while still being able 3<http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=doc/README.seri…>to use a serial console on a (different) serial port. " I am not sure I undertand what is ment in the words "modem dial-in / dial-out". What is actually the benefit of using multiple serial (#define CONFIG_MULTI_SERIAL) instead of using direcet call to ns15669 driver (for the UART'S which are not the console). If we have a case where there is only one same UART which is the console, is there any benefit of multiple serial ? Best Regards, Ran

[U-Boot] Marvell 88E1111S phy autosense
by Rick Ramstetter 04 Mar '11

Hello all, I am seeing a strange behavior regarding the Marvell 88E1111S in U-boot. In drivers/net/tsec.c, tsec_local_mdio_read() [aliased as read_phy_reg()] seems to be grabbing the value of miimstat before the phy is actually ready. This results in my board's phy being sensed as "generic" type. I have introduced code in drivers/net/tsec.c get_phy_info() to [1] retry the call to read_phy_reg() until the type sensed is not "generic" and [2] introduce a delay of 300000 nops+syncs (on an 800mhz core) between each iteration. Consistently the phy is properly detected on the 20th such iteration. I have a nearly identical board with a non-Marvell phy and I am *not* seeing this issue on that board. Does anyone have any insight into what might be going on? Affected U-boot versions are 2009.11 and 2010.12 Thanks you, -Rick R. -- J.
