[U-Boot] [PATCH 8/9 V3] new at91_emac network driver (NET_MULTI api)
by Jens Scharsig 03 Feb '10

03 Feb '10

* add's at91_emac (AT91RM9200) network driver (NET_MULTI api) * enable driver with CONFIG_DRIVER_AT91EMAC * generic PHY initialization * modify AT91RM9200 boards to use NET_MULTI driver * the drivers has been tested with LXT971 Phy and DM9161 Phy at MII and RMII interface Signed-off-by: Jens Scharsig <js_at_ng(a)scharsoft.de> --- README | 10 + board/atmel/at91rm9200dk/at91rm9200dk.c | 15 + board/atmel/at91rm9200ek/at91rm9200ek.c | 14 + board/cmc_pu2/cmc_pu2.c | 13 + board/csb637/csb637.c | 13 + board/eukrea/cpuat91/cpuat91.c | 14 + board/kb9202/kb9202.c | 13 + board/m501sk/m501sk.c | 14 + board/mp2usb/mp2usb.c | 13 + cpu/arm920t/at91rm9200/bcm5221.c | 4 +- cpu/arm920t/at91rm9200/dm9161.c | 3 +- drivers/net/Makefile | 1 + drivers/net/at91_emac.c | 498 +++++++++++++++++++++++++++++++ include/asm-arm/arch-at91/at91_emac.h | 145 +++++++++ include/configs/at91rm9200dk.h | 9 +- include/configs/at91rm9200ek.h | 8 +- include/configs/cmc_pu2.h | 8 +- include/configs/cpuat91.h | 8 +- include/configs/csb637.h | 8 +- include/configs/kb9202.h | 8 +- include/configs/m501sk.h | 9 +- include/configs/mp2usb.h | 8 +- include/netdev.h | 1 + 23 files changed, 825 insertions(+), 12 deletions(-) create mode 100644 drivers/net/at91_emac.c create mode 100644 include/asm-arm/arch-at91/at91_emac.h diff --git a/README b/README index 7affe10..3b9eb28 100644 --- a/README +++ b/README @@ -822,6 +822,16 @@ The following options need to be configured: - NETWORK Support (other): + CONFIG_DRIVER_AT91EMAC + Support for AT91RM9200 EMAC. + + CONFIG_RMII + Define this to use reduced MII inteface + + CONFIG_DRIVER_AT91EMAC_QUIET + If this defined, the driver is quiet. + The driver doen't show link status messages. + CONFIG_DRIVER_LAN91C96 Support for SMSC's LAN91C96 chips. diff --git a/board/atmel/at91rm9200dk/at91rm9200dk.c b/board/atmel/at91rm9200dk/at91rm9200dk.c index c761dd7..49b5fe3 100644 --- a/board/atmel/at91rm9200dk/at91rm9200dk.c +++ b/board/atmel/at91rm9200dk/at91rm9200dk.c @@ -23,9 +23,15 @@ */ #include <common.h> +#include <exports.h> +#include <netdev.h> #include <asm/arch/AT91RM9200.h> +#include <asm/io.h> + +#if defined(CONFIG_DRIVER_ETHER) #include <at91rm9200_net.h> #include <dm9161.h> +#endif DECLARE_GLOBAL_DATA_PTR;

[U-Boot] end-user firmware upgrade
by Marcel 02 Feb '10

02 Feb '10

Hi, I'm using u-boot for a while now for my AVR (ap7000) project and while happy with it as a developer tool I wonder how I can make it useful for end-user firmware upgrades. The way I think about it is that end-user can never be allowed to interact directly with u-boot. It's something I don't want and the users of my devices also. Unfortunately I can't find anything yet to how I can make it easy for my end-users to upgrade firmware of the device. I have only ethernet and USB available to end-users : 1) Using USB : This is easy for end-users because it doesn't depend on network configuration. Unfortunately there's no USB support in u-boot (at least not for my CPU). I found something at openmoko which may be suitable, but no other valid solutions so far. 2) Ethernet : No idea how to do this in an easy way. If it can be done, I'd be happy to hear about it. Either way, I have no clue if there are any options in u-boot available already to do what I want or must I implement this from scratch ? Best regards, Marcel

[U-Boot] CFI numblocks incorrect?
by Ladislav Michl 02 Feb '10

02 Feb '10

it seems CFI flash support is somehow broken. mtd->eraseregions is filled as bellow: erase size blocks correct blocks 00004000 01 01 00002000 01 02 00008000 00 01 00010000 0f 0f 'blocks' is actual numblocks field value while 'correct blocks' is expected value. flinfo gives correct results (it is AM29LV800BB). It seems to be related to cfi_mtd_set_erasesize function, but I'm too tired to debug it further. Just reporting in case anyone has time to look at it. Otherwise I'll do so at Friday. Best regards, ladis

Hi Folks, I would like to know Which all boards are tested with the C100 support in the Mainline. I have a C100 Single, Pop, EVT1, EVT2, EVT0 boards When i build the Mainline u-boot for "smdkc100_config"; make The u-boot.bin is not working out of the box. Am i missing anything, Any kinda help is greatly appreciated. -- Shine bright, (: Naveen Krishna Ch :)
