The code is based on the OpenPOWER pflash tool and a similar # sequence using DMAs can be found in the SDK U-Boot. # # The SPI calibration performs a loop on different SPI clock rates # (dividers of the AHB clock rates) and on different input delay cycles # for each SPI clock rates. The successive read results are compared to # a golden buffer, read at low speed, to select the fastest read # settings for the chip. # # The "spi-max-frequency" property is used to cap the optimize read # algorithm on some devices or controllers for which we want a safe # setting, on the FMC controller chips for instance. # # It can also be deactivated at boot time with a kernel parameter # 'optimize_read', but that was never used on the field. # # Signed-off-by: Cédric Le Goater <clg@kaod.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 cbf5c33ba2f308fc9a42c947d3478698d10fd205 # < make -s -j 120 ARCH=x86_64 O=/kisskb/build/cdrx_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # make -s -j 120 ARCH=x86_64 O=/kisskb/build/cdrx_x86_64-allnoconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/Makefile:24: CC cannot link executables.
