* dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIOIgor Opaniuk2021-02-211-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise. All occurences were replaced automatically using these bash cmds: $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C/if !CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C/if CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C)/CONFIG_IS_ENABLED(DM_I2C)/g' {} + $ find . -type f -exec sed -i 's/ifndef CONFIG_DM_I2C_GPIO/if !CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/ifdef CONFIG_DM_I2C_GPIO/if CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + $ find . -type f -exec sed -i 's/defined(CONFIG_DM_I2C_GPIO)/CONFIG_IS_ENABLED(DM_I2C_GPIO)/g' {} + Reviewed-by: Heiko Schocher <hs@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Igor Opaniuk <igor.opaniuk@foundries.io> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Priyanka Jain <priyanka.jain@nxp.com>

| | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

|/ | | | | | | | | | | | 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>

* treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2020-07-174-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

* drivers: ddr: imx8mp: Add inline ECC feature supportSherry Sun2020-07-142-0/+79
| | | | | | | | | | | | | | | | | | the DRAM Controller in i.MX8MP will support a feature called "Inline ECC". This is supported for all 3 supported DRAM technologies (LPDDR4, DDR4 and DDR3L). When this feature is enabled by software, the DRAM Controller reserves 12.5% of DRAM capacity for ECC information, and presents only the non-ECC portion (lower 87.5% of the installed capacity of DRAM) to the rest of the SoC. The DRAM memory can be divided into 8 regions so that if a use case only requires ECC protection on a subset of memory, then only that subset of memory need support inline ECC. If this occurs, then there is no performance penalty accessing the non-ECC-protected memory (no need to access ECC for this portion of the memory map). This is all configured with the DRAM Controller. Signed-off-by: Sherry Sun <sherry.sun@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
