* ARM: imx: fix typo in gpu3d_shader_selsShawn Guo2013-05-121-1/+1
| | | | | | | | There is no clock pll2_pfd9_720m. Instead it should be pll3_pfd0_720m. Fix the typo in gpu3d_shader_sels. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: Dirk Behme <dirk.behme@de.bosch.com>
* ARM: imx: replicate the diagnostic register of boot cpu into secondary coresShawn Guo2013-05-122-0/+26
| | | | | | | | | | | | The diagnostic register holds the errata bits. Mostly bootloader does not bring up secondary cores, so that when errata bits are set in bootloader, they are set only for boot cpu. But on a SMP configuration, it should be equally done on every single core. Set up the diagnostic register for secondary cores by replicating the register from boot cpu.

* ARM i.MX6: correct MLB clock configurationDirk Behme2013-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | According to the i.MX6 Dual/Quad technical reference manual (Figure 18-2. Clock Tree - Part 1) the MLB clock is directly feed by the AXI_CLK_ROOT. This is called 'axi' in our code. Note that the clock of the MLB IP block on the i.MX6 is completely independent of the PLL8 (MLB PLL). The MLB PLL isn't responsible for feeding the MLB IP block with a clock. Instead, it's used internally by the MLB module to sync the bus clock in case the MLB 6-pin interface is enabled: MediaLB Control 0 Register, MLB150_MLBC0[5], MLBPEN: 1 MediaLB 6-pin interface enabled. MLB PLL and MLB PHY is enabled in this case. I.e. the PLL8 MLB PLL has to be handled by the MLB driver and isn't needed for clocking the MLB module itself.

Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/.

The actual number of available cores can be found out from SCU. Since we do not reflect the fusing thing in device tree, the function arm_dt_init_cpu_maps() will always call set_cpu_possible(true) for 4 cores on i.MX6 Quad/Dual and 2 cores for i.MX6 DualLite/Solo. This causes failures when kernel tries to bring those unavailable cores online. For example, the following failure message will be seen when booting an i.MX6 Solo chip. CPU1: failed to come online Though kernel will still boot fine, the message is somehow annoying. Let's get rid of it by calling set_cpu_possible(false) on those unavailable cores. While at it, the set_cpu_possible(true) for available cores is removed, since it's already been done in arm_dt_init_cpu_maps(). Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Implementing the logic this way certainly saves lines in the Kconfig but it precludes those machines which select MSM_SCORPIONMP or MCT from participating in the single zImage effort because when those machines are combined with other SMP capable machines the TWD and SCU are no longer selected by default. Push the select out to the machine entries so that we can compile these machines together and still select the appropriate configs.
