[U-Boot] Update at91sam9m10g45 SoC and AT91SAM9M10G45-EK board to new style
Hello,
These two patches update the support of the AT91SAM9M10G45 SoC and the corresponding AT91SAM9M10G45-EK evaluation platform to the next AT91 organization.
For the moment, only the nandflash configuration is supported, the dataflash configuration will come later on.
Note however that the AT91 Ethernet driver doesn't work in the current master, due to the D-cache being enabled by c2dd0d45540397704de9b13287417d21049d34c6. Waiting for a proper solution to this problem, I am currently doing the testing with the following workaround:
diff --git a/arch/arm/lib/board.c b/arch/arm/lib/board.c index 90709d0..761e233 100644 --- a/arch/arm/lib/board.c +++ b/arch/arm/lib/board.c @@ -450,7 +450,9 @@ void board_init_r (gd_t *id, ulong dest_addr) * Enable D$: * I$, if needed, must be already enabled in start.S */ +#if 0 dcache_enable(); +#endif
debug ("monitor flash len: %08lX\n", monitor_flash_len); board_init(); /* Setup chipselects */
Best regards,
Thomas Petazzoni

Hello Reinhard,
Le Thu, 04 Aug 2011 13:59:18 +0000, Reinhard Meyer u-boot@emk-elektronik.de a écrit :
This patch still has the same issues I complained about at
Thanks a lot for the review. I have just posted an updated version, which I hope, fixes the various issues you mentioned.
Best regards,
Thomas
