Re: [U-Boot] [PATCH v5 4/5] mips: ath79: add spi driver

2015-12-30 Thread Antony Pavlov
bitbanging the SPI using the > generic soft-spi driver might be easier ;-/ AR9331 SPI controller has special shift register for reading received data, so you have no need in reading every single receiving MISO bit with separate gpio access, this can give a small speedup. Next, in openwrt tree there is a dirty-hacky ath79-spi linux kernel patch for very impressive SPI flash read speedup (2 MiB/s instead of 20 KiB/s, I have no precise bandwidth results at the moment). So for better performance it is reasonable to have separate ath79-spi driver. --  Best regards,   Antony Pavlov ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

t;dcache enable". I so sorry! My bad: your lowlevel_init actually does not contain any cache code. common code from arch/mips/cpu/start.S calls mips_cache_reset just after invoking lowlevel_init. > On 12/19/2015 12:16 AM, Antony Pavlov wrote: > > On Fri, 18 Dec 2015 23:24:22 +0800 >
