[U-Boot] [PATCHv8 1/2] armv8/ls1043a: fixup GIC offset for ls1043a rev1
by Zhiqiang Hou 19 Jan '17

19 Jan '17

From: Wenbin Song <wenbin.song(a)nxp.com> The LS1043A rev1.1 silicon supports two types of GIC offset: 4K alignment and 64K alignment. The bit SCFG_GIC400_ALIGN[GIC_ADDR_BIT] is used to choose which offset will be used. The LS1043A rev1.0 silicon only supports the CIG offset with 4K alignment. If GIC_ADDR_BIT bit is set, 4K alignment is used, or else 64K alignment is used. 64K alignment is the default setting. Overriding the weak smp_kick_all_cpus, the new impletment is able to detect GIC offset. The default GIC offset in kernel device tree is using 4K alignment, it need to be fixed if 64K alignment is detected.

[U-Boot] [PATCH] armv8: fsl-layerscape: Fix SECURE_BOOT config
by York Sun 19 Jan '17

19 Jan '17

Without a prompt in Kconfig, SECURE_BOOT cannot be selected by defconfig. The option was dropped unintentionally when defconfig files were cleaned up. Three targets were impacted ls1043ardb_SECURE_BOOT, ls2080ardb_SECURE_BOOT, ls2080aqds_SECURE_BOOT.

[U-Boot] [PATCH 1/4] mmc: fsl_esdhc: make GPIO support optional

19 Jan '17

There would be compiling error as below when enable driver model for esdhc. undefined reference to `dm_gpio_get_value' undefined reference to `gpio_request_by_name_nodev' This patch is to make GPIO support optional with CONFIG_DM_GPIO. Because all boards of QorIQ platform don't need it and they just check register for CD/WP status, only some boards of i.MX platform require this.

[U-Boot] [PATCHv5 1/2] armv8/fsl-lsch2: refactor the clock system initialization
by Zhiqiang Hou 19 Jan '17

19 Jan '17

From: Hou Zhiqiang <Zhiqiang.Hou(a)nxp.com> Up to now, there are 3 kind of SoCs under Layerscape Chassis 2, like LS1043A, LS1046A and LS1012A. But the clocks tree has a lot of differences, for instance, the IP modules have different dividers to derive its clock from Platform PLL. And the core cluster PLL and platform PLL maybe have different reference clocks, such as LS1012A. Another problem is which clock/PLL should be described by sys_info->freq_systembus, it is confused in Layerscape Chissis 2. This patch is to bind the sys_info->freq_systembus to the Platform PLL, and handle the different divider of IP modules separately between different SoCs, and separate reference clocks of core cluster PLL and platform PLL.

[U-Boot] [PATCHv2 1/2] armv8: Enable CPUECTLR.SMPEN for coherency
by Zhiqiang Hou 19 Jan '17

19 Jan '17

From: Mingkai Hu <mingkai.hu(a)nxp.com> For A53, data coherency is enabled only when the CPUECTLR.SMPEN bit is set. The SMPEN bit should be set before enabling the data cache. If not enabled, the cache is not coherent with other cores and data corruption could occur. For A57/A72, SMPEN bit enables the processor to receive instruction cache and TLB maintenance operations broadcast from other processors in the cluster. This bit should be set before enabling the caches and MMU, or performing any cache and TLB maintenance operations.

[U-Boot] [PATCH 1/2] armv8: ls1012: added usb nodes in dts
by yuantian.tang＠nxp.com 19 Jan '17

19 Jan '17

From: Tang Yuantian <Yuantian.Tang(a)nxp.com> The LS1012A processor has two integrated USB controllers. One is USB2.0 controller, the other is USB3.0 controller that allow direct connection to the USB ports with appropriate protection circuitry and power supplies.

[U-Boot] [PATCHv2 1/2] ARMv8/fsl-layerscape: Correct the OCRAM size
by Zhiqiang Hou 19 Jan '17

19 Jan '17

From: Hou Zhiqiang <Zhiqiang.Hou(a)nxp.com> The real size of OCRAM is 128KiB, so correct the size of OCRAM. And OCRAM reserved 2MiB space, then add a new macro to describe it, which is used for MMU setup.
