[PATCH 0/7] hw/sd: Use sdbus_read_data/sdbus_write_data for multiple bytes access

[Philippe Mathieu-Daudé]

Introduce sdbus_read_data() and sdbus_write_data() methods to
access multiple bytes on the data line of a SD bus.

I haven't named then sdbus_access_block() because I expect a
block to be a power of 2, while there is no such restriction
on the SD bus (think of SPI).

We can also simplify the bcm2835_sdhost and pl181 models, but
it is simpler to first let them use the Fifo32 API.

Philippe Mathieu-Daudé (7):
  hw/sd: Rename read/write_data() as read/write_byte()
  hw/sd: Rename sdbus_write_data() as sdbus_write_byte()
  hw/sd: Rename sdbus_read_data() as sdbus_read_byte()
  hw/sd: Add sdbus_write_data() to write multiples bytes on the data
    line
  hw/sd: Use sdbus_write_data() instead of sdbus_write_byte when
    possible
  hw/sd: Add sdbus_read_data() to read multiples bytes on the data line
  hw/sd: Use sdbus_read_data() instead of sdbus_read_byte() when
    possible
