The previous AST2500 # and AST2400 SoCs were covering a broader HCLK range [ 1 - 5 ] because # the AHB frequency was lower. # # The algorithm first reads a golden buffer at low speed and then # performs reads with different clocks and delay cycle settings to find # a breaking point. This selects the default clock frequency for the CEx # control register. The current settings are bit optimistic as we pick # the first delay giving good results. A safer approach would be to # determine an interval and choose the middle value. We might change the # approach depending on the results on other systems. # # Signed-off-by: Cédric Le Goater # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 6aa254f8d119df235963fd718d145317512963ac # < make -s -j 48 ARCH=powerpc O=/kisskb/build/cdrx_corenet32_smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- corenet32_smp_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/cdrx_corenet32_smp_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1497:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:248:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:228:19: note: 'i' was declared here /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_trigger': /kisskb/src/sound/soc/soc-pcm.c:1074:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_bespoke_trigger': /kisskb/src/sound/soc/soc-pcm.c:1092:9: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0xd151d8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xe00000) Image Name: Linux-5.4.0-rc1-g6aa254f8d119 Created: Fri Oct 4 23:19:40 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 6192001 Bytes = 6046.88 KiB = 5.91 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/cdrx_corenet32_smp_defconfig_powerpc-gcc4.6 # Build took: 0:01:58.018219
