To unprotect flash memory. The portion of flash memory that bootldr is
sitting in. That is why the value for the upper address is so small.

The h5550 has 48MB of soldered on flash memory and 128MB of SDRAM. The
pflash command is only protecting (or not protecting) flash memory. And
as I said above, it is only used to protect the portion that bootldr is
sitting in. You want to write to the rest of it (or at least up to 32MB
of it).
