In order to boot from ITCM, VINITHI must be tied LOW. INITRAM = 1
and VINITHI = 0 is the only combination that will allow this; all other
combinations of INITRAM and VINITHI will result in instructions being
fetched over the AHB bus. The following truth table shows this:
INITRAM VINITHI Descriptions ======= ======= ============ 0 0 ITCM disabled, boot from 0x0000_0000 over AHB. 0 1 ITCM disabled, boot from 0xFFFF_0000 over AHB. 1 0 ITCM enabled, boot from 0x0000_0000 over ITCM. 1 1 ITCM enabled, boot from 0xFFFF_0000 over AHB.
