2020-04-27ARM: zynq: Fix invalid check on NAND_CMD_NONE.Patrick van Gelder
The end_cmd field in the variables cmd_phase_addr and data_phase_addr contains the value 0xFF when the end_cmd equals NAND_CMD_NONE. This should be 0x00. This is caused by comparing NAND_CMD_NONE (int) with end_cmd (u8). end_cmd will be promoted by the int value -1 and therefore is not equal to 0xFF. Solved by casting NAND_CMD_NONE to u8 which will avoid int promotion.

Commit 6293b0361d9 ("mtd: nand: pxa3xx: add raw read support") added the local data_len variable in handle_data_pio() to track read size, but forgot to update the condition of drain_fifo() call. That happens to work when the layout last_chunk_size != 0. But when last_chunk_size == 0, drain_fifo() is not called to read the last chunk, which leads to "Wait timeout!!!" error. Fix this.

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.

2020-02-01mtd: rawnand: denali: set SPARE_AREA_SKIP_BYTES based on DT compatibleMasahiro Yamada
Currently, the denali NAND driver in U-Boot configures the SPARE_AREA_SKIP_BYTES based on the CONFIG option. Recently, Linux kernel merged a patch that associates the proper value for this register with the DT compatible string. Do likewise in U-Boot too. The denali_spl.c still uses CONFIG_NAND_DENALI_SPARE_AREA_SKIP_BYTES. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-02-01mtd: rawnand: denali_dt: insert udelay() after reset deassertMasahiro Yamada
When the reset signal is de-asserted, the HW-controlled bootstrap starts running unless it is disabled in the SoC integration. It issues some commands to detect a NAND chip, and sets up registers automatically. Until this process finishes, software should avoid any register access. Without this delay function, some of UniPhier boards hangs up while executing nand_scan_ident(). (denali_read_byte() is blocked) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2020-02-01mtd: rawnand: denali: Do not reset the block before booting the kernelMarek Vasut
The Denali NAND driver in mainline Linux currently cannot deassert the reset. The upcoming Linux 5.6 will support the reset controlling, and also set up SPARE_AREA_SKIP_BYTES correctly. So, the Denali driver in the future kernel will work without relying on any bootloader or firmware. However, we still need to take care of stable kernel versions for a while. U-boot should not assert the reset of this controller.

2020-02-01mtd: rawnand: denali-spl: Add missing hardware init on SoCFPGAMarek Vasut
On Altera SoCFPGA, upon either cold-boot or power-on reset, the Denali NAND IP is initialized by the BootROM ; upon warm-reset, the Denali NAND IP is NOT initialized by BootROM. In fact, upon warm-reset, the SoCFPGA BootROM checks whether the SPL image in on-chip RAM is valid and if so, completely skips re-loading the SPL from the boot media. This does sometimes lead to problems where the software left the boot media in inconsistent state before warm-reset, and because the BootROM does not reset the boot media, the boot media is left in this inconsistent state, often until another component attempts to access the boot media and fails with an difficult to debug failure. To mitigate this problem, the SPL on Altera SoCFPGA always resets all the IPs on the SoC early on boot. This results in a couple of register values, pre-programmed by the BootROM, to be lost during this reset. To restore correct operation of the IP on SoCFPGA, these values must be programmed back into the controller by the driver. Note that on other SoCs which do not use the HW-controlled bootstrap, more registers may have to be programmed. This also aligns the SPL behavior with the full Denali NAND driver, which sets these values in denali_hw_init().

Move MTD-related lines out of the root Makefile. Put them in their respective directories. Enclose some of these new lines to skip them when building the SPL. MTD core files and some MTD device drivers are compiled in a mtd.o object and included in the final object only if MTD support is required (there are two different symbols for that, one for U-Boot and one for the SPL). Now that all defconfigs have been fixed, we can stop the logic where enabling a command selects the core files to compile.

The 'sf' command is not supposed to rely on the MTD stack, but both 'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite their location, these functions do not depend at all on the MTD stack. This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is selected, which is inconsistent with the current situation.
