2019-10-11arm: omap: emif-common: Fix memory priming for ECCKrunal Bhargav
Before the priming begins, we need to disable RMW (Read Modify Write) and disable ECC verification for read accesses. By default, the EMIF tool enables RMW and read accesses in the EMIF_ECC_CTRL_REG. Signed-off-by: Krunal Bhargav <k-bhargav@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-10-11arm: omap: emif-common: Disable interleavingKrunal Bhargav
If ECC is enabled, we need to ensure interleaving is disabled for higher address space. Signed-off-by: Krunal Bhargav <k-bhargav@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-10-11arm: omap: emif-common: Fix ecc address calculationLokesh Vutla
ecc_address_range registers contains the start address and end address of the DDR address space. But the ddr driver is assuming the register contains the start address and size of the DDR address space. Because of this the ecc enabling is failing for the 2nd range of ecc addresses. Fix this calculation. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-19arm: emif-common: Add suppport for enabling ECCLokesh Vutla
For data integrity, the EMIF1 supports ECC on the data written or read from the SDRAM. Add support for enabling ECC support in EMIF1. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Krunal Bhargav <k-bhargav@ti.com>
2018-01-19arm: emif-common: Add ecc specific emif registersLokesh Vutla
This is a slight difference in emif_ddr_phy_status register offsets for DRA7xx EMIF and older versions. And ecc registers are available only in DRA7xx EMIC. Add support for this difference and ecc registers. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

2016-11-21arm: Introduce arch/arm/mach-omap2 for OMAP2 derivative platformsTom Rini
This moves what was in arch/arm/cpu/armv7/omap-common in to arch/arm/mach-omap2 and moves arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2 as subdirectories. All refernces to the former locations are updated to the current locations. For the logic to decide what our outputs are, consolidate the tests into a single config.mk rather than including 4.
