* arm: mach-omap: xload: Enable network interfaceTeresa Remmet2018-11-161-0/+2
| | | | | | | | | Since f0624a701513 ("net: Do not route traffic to interfaces that are not up") interfaces need to be "up" before used. To make enthernet boot work again enable the interface after dhcp is set up. Signed-off-by: Teresa Remmet <t.remmet@phytec.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: omap: xload: Fix network boot filenameSascha Hauer2018-09-181-2/+5
| | | | | | | | | | | | The dhcp code no longer exports the "bootfile" environment variable. It now uses global.dhcp.bootfile. Since global variable support is not necessarily part of the MLO we instead use struct dhcp_result * to get the bootfile information.

* net: dhcp: reworkSascha Hauer2017-12-141-1/+1
| | | | | | | | | | | | | | | The DHCP code is a mess. It is not clear which options are sent to the server and which options are returned from the server. Also environment variables are read from and written to all over the place. This patch cleans this up. There now is struct dhcp_req_param which is used for options sent to the server and struct dhcp_result which contains the values sent from the server. The values from the server are written to the barebox variables in a single place. Also it's now possible to call the dhcp code without modifying barebox variables at all, storing the result only in the dhcp result struct. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: dhcp: Allow to specify network deviceSascha Hauer2017-12-141-1/+9
| | | | | | | | | Instead of allowing to DHCP only on the "current" network device, allow to specify the desired network device. This is a first step to get rid of the concept of a "current" network device. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-2/+2
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* xload: be more flexible when searching for second stage bootloader.Vicente Bergas2015-10-021-1/+3
| | | | | | | | | | | | | | | | A first stage bootloader can read fat and ext4 filesystems, and even both can be compiled-in at the same time. But then xload has a hardcoded fat filesystem mount option which renders ext4 unusable. This patch tries to mount it as ext4 if the fat attempt fails. Then, a typical use case of an ext4 formatted filesystem is it to be a standard linux filesystem, which contains boot-related files in /boot. So, when searching for the second stage bootloader, try /boot/barebox.bin after not finding it in /barebox.bin Signed-off-by: Vicente Bergas <vicencb@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* ARM: OMAP: Add omap3 USB loader toolSascha Hauer2015-07-021-2/+6
| | | | | | | | | | | | The OMAP3 supports uploading the first stage bootloader via USB. The ROM leaves the MUSB controller enabled and it can then be used to upload a 2nd stage image. This patch adds the omap3-usb-loader tool and the necessary barebox support to upload the 2nd stage image. The omap usb loader tool is downloaded from https://github.com/grant-h/omap_loader and changed to also accept CHSETTINGS images. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* move file helper functions to separate fileSascha Hauer2014-08-071-0/+1
| | | | | | | | | | We have our file helper functions in several places. Move them all to lib/libfile.c. With this we no longer have file helpers in fs/fs.c which contains the core fs functions and no functions in lib/libbb.c which are not from busybox.

* ARM: OMAP: register OMAP specific barebox bootm handlerSascha Hauer2013-09-271-8/+2
| | | | | | | | | The OMAP ROM code passes the boot information via r0 to the bootloader. Add an OMAP specific barebox handler to pass this information to the next stage. This allows us to chainload bootloaders without loosing the information where we booted from. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: omap: Allow to set mmc devname used for bootingSascha Hauer2013-08-271-3/+16
| | | | | | | | | | | This adds a omap_set_bootmmc_devname function which can be used to specify the MMC boot device. In an xload configuration this is then used to load the next stage. In a regular build this is used to mount /boot. Also a device_detect_by_name is added to allow to disable probing for sd/mmc cards during startup. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: omap: store boot source info from ROM loaderTeresa Gámez2013-07-101-2/+6
| | | | | | | | | | | | | | | | | | The ROM loader passes the address of a buffer to the MLO in register 0. Store this data so we can find the boot source later. On the same way the bootinformation are passed to the barebox, then. It has to be enshured that r0 contains always the buffer or the boot source detection will not work. Applied this on all OMAPs. This patch is based on work of Jan Luebbe <jlu@pengutronix.de>. Compile tested on all OMAP boards. Tested on pcm049, phyCARD-A-L1 and pcm051.

* startup: call a barebox_main function pointer at the end of the startupSascha Hauer2013-01-201-1/+10
| | | | | | | | | | | | | | | | | Currently Kconfig dependencies are used to allow non-interactive builds. This leads to problems in Kconfig getting the dependencies right. This patch adds a barebox_main function pointer which is called at the end of the startup process. This defaults to run_shell when a shell is enabled. With this the HAVE_NOSHELL Kconfig variable can be removed. Non interactive builds can now be enabled for every board allowing to compile a binary without further Kconfig dependencies. This also allows for more flexibility, for example boards may decide to try non-interactive startup first and call run_shell if that fails. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
