[U-Boot-Users] Uboot-V2: ARM: towards a common start-arm.S

Hi Sascha, I think we dont have a seperate list for uboot-v2, so, just wanted to know the opinion of having a single arch/arm/cpu/start-arm.S instead of multiple start-arm files. essentially providing hooks to arch,soc,board specific preinits can allow us to reuse major chunk of code.. I have attached a sample start-arm.S (modified from start-arm920t.S) as reference. Do let me know your comments and view as to how the initial handling can be made abstract enough to plug into requirements of future SOCs, boards etc. I am looking not to mash in #ifdef ARCH_XYZ for each of the SOC implementation I plan on doing.

[U-Boot-Users] Possible Bug in at32ap mmc driver atmel_mci.c
by Gururaja Hebbar K R 18 Mar '08

18 Mar '08

Hi, I am trying to port mmc driver to my board with little assistance from atmel_mci driver. While i was trying to understand the mmc_cmd function, i think i found a bug in it. File -> uboot-1.3.1\cpu\at32ap\atmel_mci.c Function -> static int mmc_cmd(unsigned long cmd, unsigned long arg, void *resp, unsigned long flags) In Function, mmc_cmd , variable "error_flags" is 1st assigned to ERROR_FLAGS and then modified according to response type. error_flags = ERROR_FLAGS; if (!(flags & RESP_NO_CRC)) error_flags |= MMCI_BIT(RCRCE); However once the command is sent and a response is received, the driver checks for status if (status & ERROR_FLAGS) { printf("mmc: command %lu failed (status: 0x%08lx)\n", cmd, status); return -EIO; } But here, it checks for ERROR_FLAGS, while i think it was suppose to check for error_flags. Kindly correct me if i am wrong. Thanks in advance Regards Gururaja

[U-Boot-Users] Possible memory leak in cpu/ppc4xx/4xx_enet.c
by Dave Littell 18 Mar '08

18 Mar '08

Hi all, I've seen an issue with my 1.3.1-based port of U-Boot where a relatively large number of pings issued from the command line will ultimately fail with the message: Cannot allocate private hw data for eth_device... I looked around this message and it seems that ppc_4xx_eth_initialize() malloc()’s a EMAC_4XX_HW_PST structure and assigns it to dev->priv. However, nothing ever frees this buffer so standing on a ping will ultimately pull down all the available memory. One fix might be to free( dev->priv ) at the end of ppc_4xx_eth_halt(). I tried this today and noted no ill effects. Thanks, Dave
