[U-Boot] [PATCH 0/4] mips: bmips: add HSSPI support

[Álvaro Fernández Rojas]

BCM63xx HSSPI controller has the same issue as BCM63xx SPI controller: it
doesn't allow keeping CS active between transfers.
However, this controller allows changing CS polarities, which is used in the
linux upstream driver to manage CS as desired.
