*AND* fixing the name of the operation.

The pre-existing erase operations were:

 #define OPCODE_BE_4K            0x20    /* Erase 4KiB block */
 #define OPCODE_BE_32K           0x52    /* Erase 32KiB block */
 #define OPCODE_SE               0xd8    /* Sector erase (usually 64KiB) */

So I'm quite puzzled why you would call the chip erase
opcode a "block erase" opcode ... it's not a 4K block,
not a 32K block, not a sector (of, usually, 64K).

It's more typically something like multiple MBytes.

Having read or skimmed several dozen SPI flash specs,
none of them called chip erase a "block erase" operation.
