Setting MPU clock speed in x-loader for AM3715
How can I setup the MPU clock rate to 1GHz in the x-loader board initialisation code? I gather I need to modify some values used in the function "void prcm_init(void)" to reconfigure the PLL's. But what changes should I make or where can I find info for calculating PLL config values.
I want to do it in bootloader as we dont wish to have frequency scaling or smartreflex enabled on our kernel.
AM35x TRM section "4.7.6 DPLL Control" have the details of DPLL1 (MPU) configuration (same document applicable to AM3715).
In x-loader after this line "/* MPU DPLL (unlocked already) */" you have to change the M, N and etc values.
