* sunxi: use CONFIG_SYS_CLK_FREQ to set cpu clockIain Paton2015-03-29-3/+1
| | | | | | | | | | | | | | | make the CPU clock selectable via Kconfig this removes the sunxi specific CONFIG_CLK_FULL_SPEED defined in each soc header and replaces it's use in board/sunxi/board.c with CONFIG_SYS_CLK_FREQ from Kconfig which allows us to configure board specific frequency on boot Signed-off-by: Iain Paton <ipaton0@gmail.com> [hdegoede@redhat.com s/CONFIG_SYS_CLK_FREQ/CONFIG_TIMER_CLK_FREQ/ for the arch-timer clk speed on sun7i to fix mis-compile on sun7i] Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernelsSiarhei Siamashka2015-02-21-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option, which makes it go out of its way in limiting the selection of PLL clock frequencies and PMIC voltages in order not to upset outdated buggy sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set, then booting such old kernels exhibits various failures at runtime. This is very user unfriendly, and there were already several incidents when people wasted their time being hit by these runtime failures and trying to debug them. The right solution is not to add hacks and workarounds to the mainline U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact, the updated sunxi-3.4 kernels already exist. Still we need to follow the 'Principle of Least Surprise' and U-Boot needs to ensure that the old buggy kernels are not getting happily booted when the CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch addresses this particular issue. This patch makes U-Boot store the 'compatibility revision' number in the top 4 bits of the machine id and pass it to the kernel. The old buggy kernels will fail to load with a very much googlable error message on the serial console (the "r1 = 0x100010bb" part of it): "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)" This error message can be documented in the linux-sunxi wiki with proper explanations about how to resolve this situation and where to get the necessary bugfixes for the sunxi-3.4 kernel. The fixed sunxi-3.4 kernels implement a revision compatibility check and clear the top 4 bits of the machine id if everything is alright. By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4 kernel effectively certifies that it has the PLL5 clock speed and AXP209 DCDC3 voltage fixes applied. It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option in U-Boot if the user desires to use an outdated unpatched sunxi-3.4 kernel.

* sunxi: Use a common CONFIG_SYS_PROMPTIan Campbell2015-01-23-1/+0
| | | | | | | | | | | The CPU info is already logged during boot e.g. CPU: Allwinner A20 (SUN7I) so the prompt is just one more thing to change for each new SoC, just makes it "sunxi#" instead.

* ARM: HYP/non-sec: Fix the ARCH Timer frequency setting.Xiubo Li2014-12-11-0/+1
| | | | | | | | | | | | For some SoCs, the system clock frequency may not equal to the ARCH Timer's frequency. This patch uses the CONFIG_TIMER_CLK_FREQ instead of CONFIG_SYS_CLK_FREQ, then the system clock macro and arch timer macor could be set separately and without interfering each other.

| | | | | | | | | | | | | Many people are still using old linux-sunxi-3.4 kernels on sunxi devices, adding the proper MACH_TYPE defines for this allows people to switch to upstream u-boot, so that we can stop maintaining the linux-sunxi u-boot fork.
