[U-Boot] [PATCH V5 1/6] imx: add cpu type for i.MX6QP/DP
Add cpu type for i.MX6QP/DP.
This patch also fix is_mx6dqp(), since get_cpu_rev can return MXC_CPU_MX6QP and MXC_CPU_MX6DP, we should use: (is_cpu_type(MXC_CPU_MX6QP) || is_cpu_type(MXC_CPU_MX6DP)).

Changes v5: Refine commit msg Add Stefano's Acked-by
Changes v4: Address Fabio's comments, Change Quad-Plus to Dual-Plus for i.MX6DP.
Changes v3: New patch This patch is to make print_cpuinfo display correct cpu info,and fix is_mx6dqp
Changes v2: none

Since i.MX6QP changes some CCM registers, so modify the clocks settings to follow the hardware changes.
In c files, use runtime check and discard #ifdef.

Changes v4: Add Fabio's Reviewed-by
Changes v3: Move bit definition to crm_regs.h.
Changes v2: 1. Remove #ifdef, but use runtime check 2. A few bit definitions are introduced in c files, because to other platforms the macro will make compilation fail, also there are no other places refer the bit macro definitions.

Since the i.MX6QP has fixed the issue in boot ROM, so remove the workaround for i.MX6QP.

1. Add DDR script for mx6qpsabreauto board. 2. On CPU3 board, enet RGMII tx clock is from internal PLL. Set the GPR5[9] and init the enet pll output to 125Mhz. 3. On CPU3 board, SW1ABC=VDDSOC_IN, SW2=VDDARM_IN.

Changes v3: 1. runtime setting DTB 2. In this patch, we still add a new config mx6qpsabreauto_config, since SPL is not supported now, and IMX_CONFIG is needed at build time, so add this config. All the patches in this patch set have been reworked with CONFIG_MX6QP removed to align with runtime check, but this IMX_CONFIG is needed at build time. Future, when SPL is converted, this config can be removed.
Changes v2: 1. Remove unused macro in current upstream uboot. 2. setup_fec, remove non 6qp code. Add comments for gpr setting. 3. mx6qp.cfg is still same with v1. The settings is from IC and passed memory ddr stress test. Since we current have no plan to add SPL, so leave settings unchanged.

Note: In this patch, we still add a new config mx6qpsabreauto_config, since SPL is not supported now, and IMX_CONFIG is needed at build time, so add this config. Future, when SPL is converted, this config can be removed.

- In this patch, we still add a new config mx6qpsabreauto_config, since SPL is not supported now, and IMX_CONFIG is needed at build time, so add this config. All the patches in this patch set have been reworked with CONFIG_MX6QP removed to align with runtime check, but this IMX_CONFIG is needed at build time. Future, when SPL is converted, this config can be removed.
Changes v2:
- Remove unused macro in current upstream uboot.

Add cpu type for i.MX6QP/DP.
This patch also fix is_mx6dqp(), since get_cpu_rev can return MXC_CPU_MX6QP and MXC_CPU_MX6DP, we should use: (is_cpu_type(MXC_CPU_MX6QP) || is_cpu_type(MXC_CPU_MX6DP)).
Signed-off-by: Peng Fan Peng.Fan@freescale.com Acked-by: Stefano Babic sbabic@denx.de
Changes v5: Refine commit msg Add Stefano's Acked-by
Changes v4: Address Fabio's comments, Change Quad-Plus to Dual-Plus for i.MX6DP.
Changes v3: New patch This patch is to make print_cpuinfo display correct cpu info,and fix is_mx6dqp
Changes v2: none
