+Alternative boot method (DA850 EVM only):
+For the DA850 EVM an SPL (secondary program loader, see doc/README.SPL)
+is provided to load U-Boot directly from SPI flash. In this case, the
+SPL does the low level initialization that is otherwise done by the SPL.
+To build U-Boot with this SPL, do
+make da850evm_config
+make u-boot.ais
+and program the resulting u-boot.ais file to the SPI flash of the DA850 EVM.
+
+Environment Variables
+=====================
+
+The DA850 EVM allows the user to specify the maximum cpu clock allowed by the
+silicon, in Hz, via an environment variable "maxcpuclk".
+
+The maximum clock rate allowed depends on the silicon populated on the EVM.
+Please make sure you understand the restrictions placed on this clock in the
+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
+is used to obtain this information.
