* ARM iMX53: avoid magic number addressing for internal RAMAlexander Kurz2016-06-271-2/+3
| | | | | | | | | The imx53 SOC features 128kB of internal SRAM which is commonly used in early stages of barebox to store the stack. Avoid magic numbers while addressing this RAM. Signed-off-by: Alexander Kurz <akurz@blala.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: i.MX: remove unused imx-flash-header.hSascha Hauer2016-04-011-1/+0
| | | | | | | All i.MX images are nowadays built with the imx-image tool, so we do not need the header files and Kconfig options anymore. Remove them. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* mx53-qsb: Fix boot hang during reboot stress testFabio Estevam2015-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the DDR init sequence the same way as done by aee0013e53b339a5 from U-boot in order to prevent the boot hang under reboot stress test. Quoting this commit log: "Currently by running the following test: => setenv bootcmd reset => save => reset , we observe a hang after approximately 20-30 minutes of stress reboot test. Investigation of this issue revealed that when a single DDR chip select is used, the hang does not happen. It only happens when the two chip selects are active. MX53 reference manual states at "28.6.2 Memory ZQ calibration sequence": "The controller must keep the memory lines quiet (except for CK) for the ZQ calibration time as defined in the Jedec (512 cycles for ZQCL after reset, 256 for other ZQCL and 64 for ZQCS)." According to the SDE_0 and SDE_1 bit descriptions from register ESDCTL_ESDCTL: "Writing 1 to SDE0 or SDE1 will initiate power up delays as JEDEC defines. Power up delays are a function of the configured memory type (DDR2/DDR3/LPDDR2)" So make sure to activate one chip select at time (CS0 first and then CS1 later), so that the required JEDEC delay is respected for each chip select. With this change applied the board has gone through three days of reboot stress test without any hang."

* Add support for metadata in barebox imagesSascha Hauer2014-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's often useful to get some information about a barebox image before starting or flashing it. This patch introduces barebox Image MetaData (IMD). When enabled a barebox image will contain a list of tags containing the desired information. We have tags for: - the barebox release (2014.07.0-00160-g035de50-dirty) - the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014) - the board model the image is intended for - the device tree toplevel compatible property Also there is an additional generic key-value store which stores parameters for which no dedicated tag exists. In this patch it is used for the memory size an image supports. Since there is no fixed offset in a barebox image which can be used for storing the information, the metadata is stored somewhere in the image and found by iterating over the image. This works for most image types, but obviously not for SoC images which are encoded or encrypted in some way. There is a 'imd' tool compiled from the same sources for barebox, for the compile host and for the target, so the metadata information is available whereever needed. For device tree boards the model and of_compatible tags are automatically generated. Example output of the imd tool for a Phytec phyFLEX image: build: #889 Wed Jul 30 16:08:54 CEST 2014 release: 2014.07.0-00167-g6b2070d-dirty parameter: memsize=1024 of_compatible: phytec,imx6x-pbab01 phytec,imx6dl-pfla02 fsl,imx6dl model: Phytec phyFLEX-i.MX6 Duallite Carrier-Board Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: i.MX: bbu: remove dcd arguments from bbu registrationSascha Hauer2014-05-091-5/+1
| | | | | | | | | | | The i.MX barebox update handlers take an optional dcd table as argument. This can be used to add the correct dcd data to the image before flashing it. This mechanism is quite complicated and largely unused, so remove it. With this it is only possible to flash the exact image passed to barebox_update, which is what is mostly done anyway.
