STM32 and EFM32 SPI drivers adopted an incompatible conventions somewhere along the line. The set the number of bits to negative when calling SPI_SETBITS which had the magical side-effect of setting LSB first order of bit transmission. This is not only a hokey way to pass control information but is supported by no other SPI drivers.
...
This change three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the implementations of SPI_SETBITS in the STM32 and EFM32 derivers so that negated bit numbers are simply errors and it adds the SPI_HWFEATURES method that can set the LSB bit order, and (3) It changes all calls with negative number of bits from all drivers: The number of bits is now always positive and SPI_HWFEATUREs is called with HWFEAT_LSBFIRST to set the bit order.

FAT performance improvement. In large files, seeking to a position fromt he beginning of the file can be very time consuming. ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted time since we are going to seek to the same position. This fix short-circutes fat_seek() in all cases where we attempt to seek to curren position.
