![]() These functions are part of the Linux 4.6 sync. They are being added before the main sync patch in order to make it easier to address the issue across all NAND drivers (many/most of which do not closely track their Linux counterparts) separately from other merge issues.

MEMORY MAP UNDER U-BOOT AND LINUX KERNEL =========================================== 2.1. System memory map: Flash: 0x00000000-0x3FFFFFFF (1024MB) DDR: 0x40000000-0x7FFFFFFF (1024MB) SRAM: 0x80000000-0x8FFFFFFF (256MB) IP: 0xF0000000-0xFFFFFFFF (256MB) 2.2. For the initial bringup, we adopted a consistent memory scheme between U-Boot and linux kernel, you can customize it based on your system requirements: Flash0: 0x00000000-0x00FFFFFF (16MB) DDR: 0x40000000-0x4FFFFFFF (256MB) SRAM: 0x80000000-0x80007FFF (32KB) IP: 0xFC000000-0xFC0FFFFF (64KB) 3. COMPILATION ============== 3.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or uClinux version) from codesourcery.com was used. Download it from: http://www.codesourcery.com/gnu_toolchains/coldfire/download.html 3.2 Compilation export CROSS_COMPILE=cross-compile-prefix cd u-boot-1.x.x make distclean make M5373EVB_config make 4.
