If your U-Boot is configured for 32 bits, there's no benefit to =20 enabling CONFIG_PHYS_64BIT (unless you're remapping things yourself, =20 such as moving the PCIe windows), and it can slow things down. > 4.

It's generally good to use more recent code for the various =20 improvements and fixes it contains, but I don't know of a specific =20 p1021-related requirement. Note that this list is for upstream Linux; =20 for help with Freescale SDKs go to https://community.freescale.com/ Also note that p1021rdb-pc is supported in upstream Linux; you do not =20 need to use the SDK at all unless there is something specific you need =20 beyond basic board support. > 5.UMCC driver is available in linux driver ?
