This series introduces an initial SPI EEPROM driver model uclass,
analogous to the existing I2C EEPROM support, currently providing
read-only access. Patch 2 adds a sandbox emulator and a test/dm test.

v4 addresses Simon Glass's review of v3: the emulator now frees its
backing store in a remove() method, and sandbox_spi_emul_get() gets
full kerneldoc. Patch 1 is unchanged.
