* ARM: Cleanup stack offset cargo cultSascha Hauer2019-09-091-1/+1
| | | | | | | | | Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16 bytes from the stack top. This is unnecessary as on ARM we have a stack that decrements before storing values. Substracting this offset probably goes back to the U-Boot version we forked from. Stop this now.

* ARM: at91: fix at91sama5_get_ddram_size for sama5d4Ahmad Fatoum2019-05-271-1/+1
| | | | | | | | | | | | | | | | | at91sama5_get_ddram_size() is despite the name specific to the sama5d3 which it was added alongside of. sama5d4 board code continues to use it, but accessing SAMA5D3_BASE_MPDDRC (0xffffea00) on a sama5d4 should result in a Data Abort (Datasheet Figure 5-1).. Fix this by giving at91sama5_get_ddram_size the mpddrc base address as argument and migrate users to use one of two helpers that specify the base address. Tested-by: Sam Ravnborg <sam@ravnborg.org> [afa: Sam didn't test this exact change, but tested the use of the critical part: accessing a different register] Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: boards: Harmonize barebox_arm_reset_vector() prototypeSascha Hauer2019-03-181-1/+1
| | | | | | | | | | | | barebox_arm_reset_vector() is a global function but we never provided a prototype anywhere. The prototypes differ for the different boards, so to provide a common prototype we must harmonize them. void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2) Should be suitable for all boards.

* param: make parameter functions more consistentSascha Hauer2017-04-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* defaultenv: add defaultenv-1 in boards via defaultenv_append_directory()Sascha Hauer2016-10-104-0/+5
| | | | | | | | | | | | | | | | | | | | Currently it's hardcoded for each board which defaultenv version is used. This is unfortunate since some people like the other defaultenv version better and may want to select it. This patch removes the board specific environment path CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via: if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC)) defaultenv_append_directory(defaultenv_<board>); This way we can make sure that the defaultenv-1 board specific bits are only compiled in when defaultenv-1 is actually in use. The next step is to make the defaultenv version selection a user visible choice. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
