2022-12-22ddr: fsl: Remove CONFIG_MEM_INIT_VALUETom Rini
The way all of the memory init code here works is that we pass 0xDEADBEEF around for the initial value (as it's a well known 'poison' value and so easily recognized in debuggers, etc). The only point of this CONFIG symbol was to pass in a different value for that purpose. Drop this symbol and cleanup the code slightly. Signed-off-by: Tom Rini <trini@konsulko.com>

2022-10-29dm: treewide: Do not use the return value of simple uclass iteratorMichal Suchanek
uclass_first_device/uclass_next_device return value will be removed, don't use it. With the current implementation dev is equivalent to !ret. It is redundant to check both, ret check can be replaced with dev check, and ret check inside the iteration is dead code.

2022-10-18dma: Transfer dma_ops should use DMA address typesAndrew Davis
DMA operations should function on DMA addresses, not virtual addresses. Although these are usually the same in U-Boot, it is more correct to be explicit with our types here. Signed-off-by: Andrew Davis <afd@ti.com>
2022-10-18dma: ti-edma3: Add DMA map operations before and after transfersAndrew Davis
We should clean the caches before any DMA operation and clean+invalidate after. This matches what the DMA framework does for us already but adds it to the two functions here in this driver that don't yet go through the new DMA framework. Signed-off-by: Andrew Davis <afd@ti.com>

The first AM6x device was the AM654x, but being the first we named it just AM6, since more devices have come out with this same prefix we should switch it to the normal convention of using the full name of the first compatibility device the series. This makes what device we are talking about more clear and matches all the K3 devices added since. Signed-off-by: Andrew Davis <afd@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2021-09-04dma: Add a Kconfig for legacy DMASimon Glass
We cannot use the existing DMA config for the MCD driver because it is not migrated to driver model. In order to move it to drivers/Makefile we need some sort of option for it. Add a new DMA_LEGACY option, which also acts as a signal that it should be migrated. Enable this for devkit3250 which uses CONFIG_DMA_LPC32XX which is not converted to Kconfig.

In absence of Device Manager (DM) services such as at R5 SPL stage, driver will have to natively setup TCHAN/RCHAN/RFLOW cfg registers. Add support for the same. Note that we still need to send chan/flow cfg message to TIFS via TISCI client driver in order to open up firewalls around chan/flow but setting up of cfg registers is handled locally.

Calling calloc() for 0 members does not make any sense. Setting ch_priv->busy_desc = NULL for ch_priv->desc_cnt > 0 is equally unreasonable. The current code will lead to a NULL dereference in bcm6348_iudma_enable(). The assignments for ch_priv->busy_desc are obviously swapped. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-03-03dma: ti: k3-udma: Mark flow id as valid parameter for RX channel configLokesh Vutla
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.

2020-02-19dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>Masahiro Yamada
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 <linux/dma-mapping.h>, and make all drivers to include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>. If we need to differentiate them for some architectures, we can move the generic definitions to <asm-generic/dma-mapping.h>. 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.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
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.
