2014-08-20mx6: add support of multi-processor commandGabriel Huau
This allows u-boot to load different OS or Bare Metal application on different cores of the i.MX6 SoC. For example: running Android on cpu0 and a RT OS like QNX/FreeRTOS on cpu1. Signed-off-by: Gabriel Huau <contact@huau-gabriel.fr> Acked-by: Stefano Babic <sbabic@denx.de>
2014-06-17mx6: drop ARM errata 742230Shawn Guo
Commit e9fd66defd7e (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables errata 742230 for imx6, because it helps remove one reboot issue. However, this errata does not really apply on imx6, because Cortex-A9 on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2. At a later time, commit f71cbfe3ca5d (ARM: Add workaround for Cortex-A9 errata 794072) adds support of errata 794072, which applies to all Cortex-A9 revisions. As the workaround for both errata are exactly same, it makes a lot more sense to select 794072 instead of 742230 for imx6. Since we already enable 794072 for imx6, it's time to drop errata 742230 to avoid confusion. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Acked-by: Nitin Garg <nitin.garg@freescale.com>
2014-04-07MX6: Enable ARM errata workaround 794072 and 761320Nitin Garg
Since MX6 is Cortex-A9 r2p10, enable software workaround for errata 794072 and 761320. Signed-off-by: Nitin Garg <nitin.garg@freescale.com>
2014-02-11mx6: Enable L2 cache supportFabio Estevam
Add L2 cache support and enable it by default. Configure the L2 cache in the same way as done by FSL kernel: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-mx6/mm.c?h=imx_3.0.35_4.1.0 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Dirk Behme <dirk.behme@gmail.com> Acked-by: Stefano Babic <sbabic@denx.de>
2014-01-02mx6: soc: Add the required LDO ramp up delayFabio Estevam
When changing LDO voltages we need to wait for the required amount of time for the voltage to settle. Also, as the timer is still not available when arch_cpu_init() is called, we need to call it later at board_postclk_init() phase. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
2013-04-17ARM: mx6: define CONFIG_ARM_ERRATA_742230Shawn Guo
The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is claimed for Cortex-A9 (r1p0..r2p2). Though i.MX6 uses a newer revision than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be fixed by applying the workaround for this errata. So for safety, let's define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-03-07ARM: mx6: use common CPU errata config optionsStephen Warren
Now that U-Boot has common CONFIG_ options to work around some ARM CPU errata, enable the relevant options on MX6, and remove the custom lowlevel_init.S, since it's just duplicated code now.
