mtd: nand: support GPMI NAND driver for i.MX8

2020-05-10T18:55:20Z

enable the GPMI NAND driver for i.MX8, i.MX8 use similar controller as i.MX8M - register definition for i.mx8 - DMA structure must be 32bit address Signed-off-by: Peng Fan

mxs_nand: Add support for i.MX8M

2020-05-10T18:55:20Z

Update the gpmi/apbh_dma/bch drivers and relevant registers for i.MX8M. Signed-off-by: Ye Li Signed-off-by: Peng Fan

dma: ti: k3-udma: Mark flow id as valid parameter for RX channel config

2020-03-03T07:38:14Z

When flow id is not marked as valid, sysfw reads the register value to get the range of flow ids that are supported. Then compares the flow range with the U-Boot's host id. This will definitely fail as board configuration doesn't assign the full range to U-Boot's host id. In order to work around this, mark the flow id as valid and pass range as 0.

dma-mapping: move dma_map_(un)single() to

2020-02-19T13:27:30Z

The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to , and make all drivers to include instead of . If we need to differentiate them for some architectures, we can move the generic definitions to . Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it. Signed-off-by: Masahiro Yamada

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

dma: Rename free() to rfree()

2020-02-06T02:33:46Z

This function name conflicts with our desire to #define free() to something else on sandbox. Since it deals with resources, rename it to rfree(). Signed-off-by: Simon Glass

dma: ti: k3-udma: Fix build warnings when building for 32 bit platforms

Cast pointers properly so as to avoid warnings when driver is built for 32 bit platforms Signed-off-by: Vignesh Raghavendra Reviewed-by: Grygorii Strashko Signed-off-by: Lokesh Vutla

dma: ti: k3-udma: Fix ring push operation for 32 bit cores

2020-01-20T04:40:28Z

UDMA always expects 64 bit address pointer of the transfer descriptor in the Ring. But on 32 bit cores like R5, pointer is always 32 bit in size. Therefore copy over 32 bit pointer value to 64 bit variable before pushing it over to the ring, so that upper 32 bits are 0s.

dma: ti: k3-udma: Switch to exposed ring mode

2020-01-20T04:40:28Z

Exposed ring mode works well with 32 bit and 64 bit cores without need for Proxies for 32 bit cores. Therefore switch to exposed ring mode. Signed-off-by: Vignesh Raghavendra Reviewed-by: Grygorii Strashko Signed-off-by: Lokesh Vutla
