Andrew Leech	30501d3f54	drivers, stm32: Support SPI/QSPI flash chips over 16MB. With a SPI flash that has more than 16MB, 32-bit addressing is required rather than the standard 24-bit. This commit adds support for 32-bit addressing so that the SPI flash commands (read/write/erase) are selected automatically depending on the size of the address being used at each operation.	2020-01-30 13:18:38 +11:00

drivers, stm32: Support SPI/QSPI flash chips over 16MB.

With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.

drivers/bus: Add QSPI abstract type with software QSPI implementation.

A new directory drivers/bus/ is introduced, which can hold implementations
of bus drivers.  A software QSPI implementation is added.
