- * Params passed in registers:

- * r1 = unlock SDRC DLL? (1 = yes, 0 = no). Only unlock DLL for
- * SDRC rates < 83MHz
- * r2 = number of MPU cycles to wait for SDRC to stabilize after
- * reprogramming the SDRC when switching to a slower MPU speed
- * r3 = increasing SDRC rate? (1 = yes, 0 = no)
- *
- * Params passed via the stack. The needed params will be copied in SRAM
- * before use by the code in SRAM (SDRAM is not accessible during SDRC
- * reconfiguration):
- * new SDRC_RFR_CTRL_0 register contents
- * new SDRC_ACTIM_CTRL_A_0 register contents
- * new SDRC_ACTIM_CTRL_B_0 register contents
- * new SDRC_MR_0 register value
- * new SDRC_RFR_CTRL_1 register contents
- * new SDRC_ACTIM_CTRL_A_1 register contents
- * new SDRC_ACTIM_CTRL_B_1 register contents
- * new SDRC_MR_1 register value
- *
- * If the param SDRC_RFR_CTRL_1 is 0, the parameters are not programmed into
- * the SDRC CS1 registers
- *
- * NOTE: This code no longer attempts to program the SDRC AC timing and MR
- * registers. This is because the code currently cannot ensure that all
- * L3 initiators (e.g., sDMA, IVA, DSS DISPC, etc.) are not accessing the
- * SDRAM when the registers are written. If the registers are changed while
- * an initiator is accessing SDRAM, memory can be corrupted and/or the SDRC
- * may enter an unpredictable state. In the future, the intent is to
- * re-enable this code in cases where we can ensure that no initiators are
- * touching the SDRAM. Until that time, users who know that their use case
- * can satisfy the above requirement can enable the CONFIG_OMAP3_SDRC_AC_TIMING
- * option.
- *
- * Richard Woodruff notes that any changes to this code must be carefully
- * audited and tested to ensure that they don't cause a TLB miss while
- * the SDRAM is inaccessible. Such a situation will crash the system
- * since it will cause the ARM MMU to attempt to walk the page tables.
- * These crashes may be intermittent.
