/*
 * This function reads SDRAM parameters (and a few CLK_RST register values) from
 * the common BCT format and writes them into PMC scratch registers (where the
 * BootROM expects them on LP0 resume). Since those store the same values in a
 * different format, we follow a "translation table" taken from Nvidia's U-Boot
 * implementation to shift bits into the right position.
 *
 * Contrary to U-Boot, we transform the same macros directly into hardcoded
 * assignments (without any pesky function calls or volatile qualifiers) to give
 * the compiler as much room for optimization as possible. For that reason, we
 * that PMC scratch register accesses should not have side effects and can be
 * arbitrarily reordered. For the few accesses that do have side-effects, the
 * code must contain explicit memory barriers.
