wl12xx: increase firmware upload chunk size
The chunk size used during firmware upload was set to 512, which is the size of a single SDIO block (or two). This is very inneficient because we send one or two blocks only per SDIO transaction and don't get the full benefits of sdio block transfers. This patch increases the chunk size to 16K. This more than doubles the transfer speed both in wl127x and wl128x chips, with greater impact on the latter: wl127x: 512 bytes chunk -> ~132ms 16384 bytes chunk -> ~57ms wl128x: 512 bytes chunk -> ~216ms 16384 bytes chunk -> ~37ms Signed-off-by: Luciano Coelho <coelho@ti.com>
