===============
For DA850 an SPL (secondary program loader, see doc/README.SPL) is provided
-to load U-Boot directly from SPI flash. The SPL takes care of the low level
+to load U-Boot from SPI flash, MMC or NAND. The SPL takes care of the low level
initialization.
-The SPL is built as u-boot.ais for all DA850 defconfigs. The resulting
-image file can be programmed to the SPI flash of the DA850 EVM/LCDK.
+The SPL is built as u-boot.ais for all DA850 defconfigs except those booting
+from NOR flash. The resulting image file can be programmed to the SPI flash

+Devices that support booting from NOR utilize execute in place (XIP) and do
+not require SPL to perform low level initialization.
Environment Variables
=====================
device specific datasheet before setting up this variable. This information is
passed to the Linux kernel using the ATAG_REVISION atag.
-If "maxcpuclk" is not defined, the configuration CONFIG_DA850_EVM_MAX_CPU_CLK
+If "maxcpuclk" is not defined, the configuration CFG_DA850_EVM_MAX_CPU_CLK
is used to obtain this information.

=======================
-CONFIG_SYS_DV_NOR_BOOT_CFG: AM18xx based boards, booting in NOR Boot mode
+CFG_SYS_DV_NOR_BOOT_CFG: AM18xx based boards, booting in NOR Boot mode
need a "NOR Boot Configuration Word" stored
in the NOR Flash. This define adds this.
