2020-07-20mtd: spinand: micron: identify SPI NAND device with Continuous Read modeShivamurthy Shastri1-0/+1
Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with the Continuous Read mode. Some of the Micron SPI NAND devices have the "Continuous Read" feature enabled by default, which does not fit the subsystem needs. In this mode, the READ CACHE command doesn't require the starting column address. The device always output the data starting from the first column of the cache register, and once the end of the cache register reached, the data output continues through the next page. With the continuous read mode, it is possible to read out the entire block using a single READ command, and once the end of the block reached, the output pins become High-Z state. However, during this mode the read command doesn't output the OOB area. Hence, we disable the feature at probe time.

2020-07-09linux/kconfig.h: create two- and three-argument versions of CONFIG_IS_ENABLEDRasmus Villemoes1-3/+45
This adds a bunch of preprocessor magic to extend the capabilities of CONFIG_IS_ENABLED. The existing semantics of CONFIG_IS_ENABLED(FOO) expanding to a 1 or 0 (depending on build context and the defined-ness or not of the appropriate CONFIG_FOO/CONFIG_SPL_FOO/CONFIG_TPL_FOO) are of course preserved. With this, one is also allowed a two-argument form CONFIG_IS_ENABLED(FOO, (something)) which expands to something precisely when CONFIG_IS_ENABLED(FOO) would expand to 1, and expands to nothing otherwise. It is, in other words, completely equivalent to the three lines #if CONFIG_IS_ENABLED(FOO) something #endif The second argument must be parenthesized in order to allow any tokens, including a trailing comma, to appear - one use case for this is precisely to make it a bit more ergonomic to build an array and only include certain items depending on .config. That should increase both readability and not least "git grep"ability. A third variant is also introduced, CONFIG_IS_ENABLED(FOO, (xxx), (yyy)) which corresponds to #if CONFIG_IS_ENABLED(FOO) xxx #else yyy #endif Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-09linux/kconfig.h: remove unused helper macrosRasmus Villemoes1-35/+5
U-Boot does not have loadable modules, and nothing currently uses any of the (CONFIG_)?IS_(BUILTIN|MODULE) macros - only the (CONFIG_)?IS_ENABLED variants are ever used. While I understand the desire to keep this somewhat synchronized with linux, we've already departed by the introduction of the CONFIG_IS_ENABLED extra logic, and deleting these makes the next patch much simpler, since I won't have to duplicate a lot of logic for no real gain (as there are no users).

2020-07-09linux/kconfig.h: simplify logic for choosing CONFIG_{SPL_, TPL_, }*Rasmus Villemoes1-19/+8
Instead of using the arg1_or_junk trick to pick between two choices, with a bit of duplication between the branches (and most of the CONFIG_TPL_BUILD case being redundant, as _IS_TPL is known to be defined to 1 in that case), simply define a prefix that we inject between CONFIG_ and the given config symbol. This only requires one level of indirection (to get the _CONFIG_PREFIX macro expanded before the token concatenation takes place), and makes it easy to, say, introduce a CONFIG_HOSTTOOL_ prefix. [I would expect most HOSTTOOL_ symbols to just be def_bool y, but it would allow us to clean up some of the ifdef HOSTCC mess in the sources shared between U-Boot and host tools.] Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-01compilers: Introduce options for forcing inlining on SPL/TPLTom Rini1-1/+1
There are cases where when we allow the compiler to decide about making inline decisions rather than forcing them it can save us space. For now, we keep the default values for inlining that we have had historically. Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Tom Rini <trini@konsulko.com>
2020-07-01compiler_types.h: Re-introduce CONFIG_OPTIMIZE_INLINING for U-BootTom Rini1-1/+10
In the Linux kernel, support for forcing inline functions to be made inline, rather than allowing the compiler to make its own choice has been removed. With respect to performance, modern GCC (and Clang) do a good job at deciding when to, or not to, inline code and there are no run-time requirements in Linux anymore. There is one downside to this, which is final binary size. On average in U-Boot removing this support grows SPL by almost 1 kilobyte. But there are cases where it shrinks the binary by making better inline choices than we had forced. Start by re-introducing CONFIG_OPTIMIZE_INLINING as a global which essentially reverts 889b3c1245de ("compiler: remove CONFIG_OPTIMIZE_INLINING entirely") from Linux.

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.
