This section discusses fast boot operations.
45.6.6.1 Normal fast boot flow
Freescale Semiconductor, Inc.
1. Software need to configure SYSCTL[INITA] to make sure 74 card clocks are
2. Software need to configure MMCBOOT[BOOTEN] to 1, and
3. Software then need to configure BLKATTR register to set block size/no.
4. Software need to configure PROCTL[DTW].
5. Software need to configure CMDARG to set argument if needed(no need in normal
finished.
MMCBOOT[BOOTMODE] to 0, and MMCBOOT[BOOTACK] to select the ack
mode or not. If need to send through DMA mode, need to configure
MMCBOOT[AUTOSABGEN] to enable automatically stop at block gap feature.
And need to configure MMCBOOT[DTOCVACK] to select the ack timeout value
according to the sd clk frequence.
