* ARM: i.MX: Add i.MX7 base architecture supportJuergen Borleis2017-01-201-0/+70
| | | | | Signed-off-by Juergen Borleis <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX25/35: Fix bootsource detectionDaniel Krüger2016-11-231-6/+6
| | | | | | | | This fixes commit 0b47f95340d801a26643e5e1f4ee05287e8ae90e for i.MX25/35. Otherwise the bootsource was just "unknown". Signed-off-by: Daniel Krueger <daniel.krueger@systec-electronic.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX53: Detect booting from USBSascha Hauer2016-09-221-0/+6
| | | | | | | The USB download mode can be detected by reading the BMOD[0|1] bits. Add support for it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: Provide bootsource functions for early boot codeSascha Hauer2016-09-221-23/+67
| | | | | | | | The regular bootsource functions only work in a running barebox, provide functions for early code. This has already been done for i.MX6, this patch adds the same functions for the other SoCs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX53: do not pass base address to imx*_boot_save_locSascha Hauer2016-09-221-6/+14
| | | | | | | The functions can determine the necessary base addresses themselves since they are SoC specific anyway. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX6: add function to get bootsource in pblSascha Hauer2015-07-161-16/+22
| | | | | | | In the pbl the regular bootsource_get cannot be used. Add a function which returns the bootsource directly with values from the hardware. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX53: fix bootsource_instance detectionSascha Hauer2014-01-271-1/+1
| | | | | | | Bootsource instance is encoded in bit 21:20 of the SBMR register, not in bit 22:21. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX6: Fix bootsource detectionPhilipp Zabel2013-06-081-7/+19
| | | | | | | | | This patch fixes boot_mode detection for non-internal boot and bootsource detection for i2c boot. Further, the bootsouce_instance is now determined for spi, i2c, and mmc/sd boot.

* ARM: i.MX53: Add bootsource instance informationSascha Hauer2013-04-041-2/+16
| | | | | | | | | The i.MX53 has the bootsource instance information stored in SBMR[21:22], expose it to the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootsource: create arch independent bootsource frameworkMarc Kleine-Budde2013-04-041-44/+13
| | | | | | | | | | | | This patch seperates the imx independent from the arch independent code. The following functions and enums are renamed: - imx_bootsource() -> bootsource_get() - imx_set_bootsource() -> bootsource_set() - enum imx_bootsource -> enum bootsource Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: rename barebox_loc to bootsourceSascha Hauer2013-04-031-4/+4
| | | | | | | | | | | Rename the barebox_loc environment variable to bootsource, since - barebox_loc is a mixture between abbriviation and fulltext which is not nice - technically it describes the source the SoC has booted from. This is not necessarily barebox but could also be some other first stage loader.

* ARM i.MX bootsource: add separate function for mx25 and mx35Marc Kleine-Budde2013-03-261-1/+21
| | | | | | | | This patch creates a seperate function for mx25 and mx35 to save it's bootsource. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX bootsource: rename imx_27_boot_save_loc -> imx27_boot_save_locMarc Kleine-Budde2013-03-261-1/+1
| | | | | | | | This patch renames imx_27_boot_save_loc() to imx27_boot_save_loc(), so that all imx*_boot_save_loc() functions follow the same nameing sheme. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX bootsource: imx_25_35_boot_save_loc: remove leftover do-nothing codeMarc Kleine-Budde2013-03-261-5/+0
| | | | | | | | | This patch removes some code leftover from: a029e32 ARM i.MX: rework bootsource setting which is now a no-op. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX bootsource: convert all imx*_boot_save_loc functions to voidMarc Kleine-Budde2013-03-261-12/+6
| | | | | | | This function gives all functions a common, i.e. void, return value. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX bootsource: convert enums from enum imx_bootsource to uppercaseMarc Kleine-Budde2013-03-261-45/+45
| | | | | | | Enums are in the same way as defines, so write them in uppercase. Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM i.MX53: set bootsource locationSascha Hauer2012-10-171-0/+35
| | | | | | | To be able to set the environment location based on the bootsource. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX: rework bootsource settingSascha Hauer2012-10-151-53/+125
| | | | | | | | | | This moves the known i.MX bootsource settings to a single file so that the code can be shared. Also we add a enum for the different boot sources so that it can be used in C Code and not only on the shell. The pcm038 board is changed to use it instead of digging in the registers manually.

* Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-171-4/+0
| | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* introduce io.hSascha Hauer2011-09-221-1/+1
| | | | | | | To allow for some generic io accessors introduce io.h and use this instead of asm/io.h throughout the tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM i.MX25/35: initialize barebox_loc earlierSascha Hauer2011-08-171-6/+2
| | | | | | | | Now that env_push_context is in a coredevice_initcall we can initialize barebox_loc earlier so that we can use it inside later initcalls. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* imx(25,35): save boot location into $barebox_loc env.Marc Reilly2011-01-191-0/+95
Saves the boot source into an environment variable so env scripts can more easily use boot source information. Note only tested on imx35. I haven't added support for any other variants because I'm not familiar with them. (And can't test them anyway).
