Command line partition table parsing on MX53

Hello!

 

Can anyone explain how to get my u-boot partions parsed via command line to the kernel to get rid of the board specific mapping (see nand_flash_partitions in mx53_evk.c)?

 

The relevant options have already been enabled in the kernel (v2.6.35.3, "Command line partition table parsing") so I'm sure the relevant functions are build in.

 

If I set the command line nothing happens.

console=ttymxc0,115200n8 video=mxcdi0fb:RGB24,XGA di0_primary ldb=di0 mtdparts=mxc_nandv2_flash.0:512k@0x0(u-boot),128k@0x80000(u-bootenv),5Mk(kernel),-(rootfs) root=/dev/nfs ip=dhcp nfsroot=192.168.1.122:/tftpboot/rootfs,v3,tcp

 

The function parse_cmdline_partitions in drivers/mtd/cmdlinepart.c is called and the parsed partitions are correct (did a printk), but why are they not created? Must these partitions additionally passed to the board specific code? Are the partitions stored in a global variable so I can assign them to the struct nand_flash_partitions?

 

Regards,

Rooney
