 *  Configure L1 cache and L1DSRAM segment
 *
 *  In addition to the 64K at address 0x11800000, the DM6446 device has another
 *  48K of physical memory at 0x11F04000 available as internal RAM,
 *  called the "L1DSRAM" segment in BIOS, and it has another adjacent 32K
 *  at 0x11F10000 that can either be used entirely for L1 cache,
 *  or split between L1 cache and more internal memory.
 *
 *  The 80K segment (48K + 32K) starts at 0x11F04000. When powered on, the
 *  device uses the upper 32K for L1 cache entirely, so BIOS by default defines
 *  the L1DSRAM segment to be 48K long and does not change the cache.
 *
 *  We can change the default behavior, by shrinking the L1 cache and adding
 *  the extra space to L1DSRAM. We can set the L1 cache to be 32K (the default)
 *  or 16K, 8K, 4K, or 0K. The corresponding L1DSRAM sizes then are 48K (the
 *  default), or 64K, 72K, 76K, or 80K.
