2019-11-20env: Finish migration of common ENV optionsTom Rini
- In ARMv8 NXP Layerscape platforms we also need to make use of CONFIG_SYS_RELOC_GD_ENV_ADDR now, do so. - On ENV_IS_IN_REMOTE, CONFIG_ENV_OFFSET is never used, drop the define to 0. - Add Kconfig entry for ENV_ADDR. - Make ENV_ADDR / ENV_OFFSET depend on the env locations that use it. - Add ENV_xxx_REDUND options that depend on their primary option and SYS_REDUNDAND_ENVIRONMENT - On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR for the pre-main-U-Boot environment location. - On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but rather it being non-zero, as it will now be zero by default. - Rework the env_offset absolute in env/embedded.o to not use CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within ENV_IS_IN_FLASH. - Migrate all platforms.

2019-01-19Kconfig: Migrate BOUNCE_BUFFERPhilipp Tomsich
The bounce buffer is used by a few drivers (most of the MMC drivers) to overcome limitations in their respective DMA implementation. This moves the configuration to Kconfig and makes it user-selectable (even though it will be a required feature to make those drivers work): the expected usage is for drivers depending on this to 'select' it unconditionally from their respective Kconfig (see follow-up patches). This commit includes a full migration using moveconfig.py to ensure that each commit compiles. To ensure bisectability we update dependencies of various drivers to now select BOUNCE_BUFFER when needed.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-16Convert all of CONFIG_CONS_INDEX to KconfigTom Rini
This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

2016-09-27ARM: tegra: increase console buffer size and sys args numBryan Wu
The Linux-for-Tegra kernel uses a very long command line. The default value of CONFIG_SYS_CBSIZE is too small to printf out the long command line and causes a message like: bootarg overflow 602+0+0+1 > 512 on the console, and the board refuses to boot. The default value of CONFIG_SYS_MAXARGS is too small to add a long long command line, and the kernel won't boot without the complete bootargs. Increasing these two config options solves this problem.

2015-09-11ARM: tegra: fix malloc region sizingStephen Warren
Commit 52a7c98a1772 "tegra-common: increase malloc pool len by dfu mmc file buffer size" updated the definition of CONFIG_SYS_MALLOC_LEN for Tegra to take account of the DFU buffer size. However, this change had no effect, since typical Tegra board config headers don't set the DFU- related defines until after tegra-common.h is included. Fix this by moving the affected conditional code to tegra-common-post.h, which is included last. Also move the definition of SYS_NONCACHED_MEMORY since it's a related and adjacent definition. Fix the condition to test for the DFU feature, rather than specifically MMC DFU support, so it applies in all cases. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2015-08-13ARM: tegra: represent RAM in 1 or 2 banksStephen Warren
Represent all available RAM in either one or two banks. The first bank describes any RAM below 4GB. The second bank describes any RAM above 4GB. This split is driven by the following requirements: - The NVIDIA L4T kernel requires separate entries in the DT /memory/reg property for memory below and above the 4GB boundary. The layout of that DT property is directly driven by the entries in the U-Boot bank array. - On systems with RAM beyond a physical address of 4GB, the potential existence of a carve-out at the end of RAM below 4GB can only be represented using multiple banks, since usable RAM is not contiguous. While making this change, add a lot more comments re: how and why RAM is represented in banks, and implement a few more "semantic" functions that define (and perhaps later detect at run-time) the size of any carve-out.

2015-08-13kconfig: add config option for shell promptNikita Kiryanov
Add option to set shell prompt string from menuconfig and migrate boards globally. The migration is done as follows: - Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the entry moved to their defconfig files. - Boards that defined some kind of #ifdef logic which selects the CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT right before the #ifdef logic and were left alone. - This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h files. This results in a streamlined default value across platforms, and includes the following files: spear-common, sunxi-common, mv-common, ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common. - Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were not updated in their respective defconfig files under the assumption that since they did not explicitly define a value, they're fine with whatever the default is. - On the other hand, boards that relied on a value defined in some <boards>_common.h file such as woodburn_common, rpi-common, bur_am335x_common, ls2085a_common, siemens_am33x_common, and omap3_evm_common, had their values moved to the respective defconfig files. - The define V_PROMPT was removed, since it is not used anywhere except for assigning a value for CONFIG_SYS_PROMPT.
