ARM: armv7: move ARMV7_PSCI_NR_CPUS to Kconfig

2016-09-07T12:48:54+00:00

Move this option to Kconfig and set its default value to 4; this
increases the number of supported CPUs for some boards.

It consumes 1KB memory per CPU for PSCI stack, but it should not
be a big deal, given the amount of memory used for the modern OSes.

ARM: armv7: move CONFIG_ARMV7_PSCI to Kconfig

2016-09-07T12:48:51+00:00

Add ARCH_SUPPORT_PSCI as a non-configurable option that platforms
can select.  Then, move CONFIG_ARMV7_PSCI, which is automatically
enabled if both ARMV7_NONSEC and ARCH_SUPPORT_PSCI are enabled.

sunxi: Add support for Allwinner A64 SoCs

2016-04-01T07:52:28+00:00

The Allwinner A64 SoC is used in the Pine64. This patch adds
all bits necessary to compile U-Boot for it running in AArch64
mode.

Unfortunately SPL is not ready yet due to legal problems, so
we need to boot using the binary boot0 for now.

sunxi/nand: Add support to the SPL for loading u-boot from internal NAND memory

2015-05-29T11:46:36+00:00

This commit adds support to the sunxi SPL to load u-boot from the internal
NAND. Note this only adds support to access the boot partitions to load
u-boot, full NAND support to load the kernel, etc. from the nand data
partition will come later.

sunxi: usb: Do not call phy_probe from hcd code

2015-05-04T14:51:55+00:00

The 2/3 usb-phys on the sunxi SoCs are really a single separate functional
block, and are modelled as such in devicetree. So once we've moved all the
sunxi usb code to the driver-model then phy_probe will be called once
for the entire block from the driver-model enumeration code.

Move to this now as this also avoids problems with phy_probe being called
multiple times once we introduce ohci support. This also allows us to get rid
of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed
to be called only once.

Since we're effectively rewriting the probe / remove functions, move them
to the end of the file while we are at it, as that is the most logical place
for them.

sunxi: use CONFIG_SYS_CLK_FREQ to set cpu clock

2015-03-29T11:36:03+00:00

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

sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernels

2015-02-21T15:54:29+00:00

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.
