[U-Boot] [PATCH v2 0/9] basic support for Allwinner A83T SOC.
by Vishnu Patekar 10 Dec '15

10 Dec '15

This patch v2 of series that adds basic support for Allwinner A83T SOC with review comments addressed. Allwinner A83T is octa-core cortex-a7 based SoC. It's clock control unit and prcm, pinmux are different from previous sun8i series. Its processor cores are arragned in two clusters 4 cores each, similar to A80. Only basic clocks are enabled pll1, pll5, pll6. SMP, display, other peripherals support is not yet supported. This enables booting kernel with initramfs, kernel patch v1 have been sent. I'll send v2 with comments addressed. Changes from v1-> v2: 1. removed CPU_V7_HAS_NONSEC, CPU_V7_HAS_VIRT, ARMV7_BOOT_SEC_DEFAULT as no smo support is added yet. 2. added AXP818 voltages description. 3. used AXP223 address for AXP818. 4. corrected the reg filed in dtsi(100 to 0x100).

[U-Boot] [PATCH] ns16550: change reg-shift property default to zero
by Thomas Chou 08 Dec '15

Change reg-shift property default to zero. When the integer property is missing, it should be taken as zero. This is consistent to Linux drivers/tty/serial/of_serial.c. The x86 and most powerpc use reg-shift of 0. Most others use reg-shift of 2. While reg-shift of 1 is rarely used.
