imx: mx7d: move MX7D to Kconfig entry

2016-03-26T13:16:12Z

If including MX7D in CONFIG_SYS_EXTRA_OPTIONS, CONFIG_ROM_UNIFIED_SECTIONS will not effect.So move MX7D to Kconfig entry from CONFIG_SYS_EXTRA_OPTIONS to "select MX7D" to boards using i.MX7 Dual. Signed-off-by: Peng Fan Cc: Stefano Babic Cc: Fabio Estevam Reviewed-by: Fabio Estevam

mx7: Distinguish between dual and solo versions

2016-03-09T11:50:39Z

imx: mx7d: isolate resources to domain 0 for A7 core

2016-02-21T10:46:26Z

In current design, if any peripheral was assigned to both A7 and M4, it will receive ipg_stop or ipg_wait when any of the 2 platforms enter low power mode. We will have a risk that, if A7 enter wait, M4 enter stop, peripheral will have chance to get ipg_stop and ipg_wait asserted same time. Also if M4 enters stop mode, A7 will have no chance to access the peripheral. There are 26 peripherals affected by this IC issue: SIM2(sim2/emvsim2) SIM1(sim1/emvsim1) UART1/UART2/UART3/UART4/UART5/UART6/UART7 SAI1/SAI2/SAI3 WDOG1/WDOG2/WDOG3/WDOG4 GPT1/GPT2/GPT3/GPT4 PWM1/PWM2/PWM3/PWM4 ENET1/ENET2 Software Workaround: The solution is to set the peripherals to Domain0 by A core, since A core in Domain0. The peripherals which will be used by M4, will be set to Domain1 by M4. For example, A core set WDOG4 to domain0, but when M4 boots up, M4 will set WDOG4 to domain1, because M4 will use WDOG4. So the peripherals are not shared by them. This way requires the uboot implemented the RDC driver and set the 26 IPs above to domain 0 only. M4 image will set the M4 to domain 1 and set peripheral which it will use to domain 1. This patch enables the CONFIG_IMX_RDC and CONFIG_IMX_BOOTAUX for i.MX7D SABRESD board, and setup the 26 IP resources to domain 0. Signed-off-by: Ye.Li Signed-off-by: Peng Fan

imx: mx7: implement functions to boot auxiliary core

2016-02-21T10:46:26Z

Implement arch_auxiliary_core_up and arch_auxiliary_core_check_up. arch_auxiliary_core_check_up is used to check whether M4 is running or not. arch_auxiliary_core_up is to boot M4 core, the m4 core will use the pc and stack which is set in arch_auxiliary_core_up to set R15 and R13 register and boot.

imx: mx7dsabresd: move mmc_get_env_devno to soc code

2016-02-04T09:13:45Z

Move mmc_get_env_devno to soc.c and rename to mmc_get_env_dev to match the one in common/env_mmc.c. Introduce a weak function board_mmc_get_env_dev. Different boards can implement this according to sdhc controller which is used by the board. Signed-off-by: Peng Fan Cc: Stefano Babic

imx: mx7: default enable MDIO open drain

2016-01-24T11:15:14Z

The management data input/output (MDIO) requires open-drain, i.MX7D TO1.0 ENET MDIO pin has no open drain, but TO1.1 supports this feature. So to TO1.1, need to enable open drain by setting bits GPR0[8:7] for TO1.1. Signed-off-by: Peng Fan Cc: Stefano Babic
