* drivers/base: fix corrupt device treeSascha Hauer2012-12-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_add_child is a very unsafe function. If called multiple times it allows setting the same device to different parents thus corrupting the siblings list. This happens regularly since: | commit c2e568d19c5c34a05a1002d25280bf113b72b752 | Author: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> | Date: Sat Nov 3 16:11:05 2012 +0100 | | bus: add bus device | | automatically add it as parent of any bus device if none already specified | | we have now a nice output per bus If for example a FATfs is mounted this nice output per bus often ends with: > `---- fat0 > `---- 0 > `---- 0x86f0000087020031-0x86f000410df27124: /dev/<NULL> > `---- sram00 > `---- 0x00000000-0xffffffffffffffff: /dev/<NULL> > `---- 0x00000000-0xffffffffffffffff: /dev/<NULL> > unable to handle NULL pointer dereference at address 0x0000000c > pc : [<87f08a20>] lr : [<87f08a04>] > sp : 86eff8c0 ip : 87f3fbde fp : ffffffff > r10: ffffffff r9 : 00000000 r8 : 00000003 > r7 : 86f075b8 r6 : 00000002 r5 : ffffffec r4 : 86f07544 > r3 : 00000000 r2 : 43f900b4 r1 : 00000020 r0 : 00000005 > Flags: Nzcv IRQs off FIQs off Mode SVC_32 > [<87f08a20>] (do_devinfo_subtree+0x90/0x130) from [<87f08a90>] (do_devinfo_subtree+0x100/0x130) > > [<87f3e070>] (unwind_backtrace+0x0/0x90) from [<87f28514>] (panic+0x28/0x3c) > [<87f28514>] (panic+0x28/0x3c) from [<87f3e4b8>] (do_exception+0x10/0x14) > [<87f3e4b8>] (do_exception+0x10/0x14) from [<87f3e544>] (do_data_abort+0x2c/0x38) > [<87f3e544>] (do_data_abort+0x2c/0x38) from [<87f3e268>] (data_abort+0x48/0x60) This patch fixes this by adding a device to its parents children list in register_device so that dev_add_child is no longer needed. This function is removed from the tree. Now callers of register_device have to clearly set the parent *before* registering a device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in-system update means to write an arbitrary file to an arbitrary device. There is no sanity check if the flashed image is of the right type or will fit onto the device. Furthermore some SoCs need a special preparation step for their images before flashing them. This adds a barebox in-system update infrastructure. Boards can register update handlers which know how to make the board bootable. The available handlers can be listed to be able to select one, different force levels give the user the chance to know it better. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Also, the console buffer is emptied when the first console is registered, even when it's not enabled. This patch cleans it up in a way that: - the console buffer is emptied once the first console is activated, not when it's registered. - Make sure that the banner is printed first, so that we can output things to the buffer before the banner is printed without ending up in having the banner in the middle of the other boot messages. - Use IS_ENABLED rather than ifdefs Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This results in a corrupt default environment. This patch fixes this by adding a cmd_env_h and changing barebox_default_env.h to FORCE. As a side effect barebox_default_env.h is no longer generated in include/generated/ but in common/ as we have to add barebox_default_env.h to $(targets) (extra-y).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dependencies for generating the environment do not work properly: - If files are removed from the defaultenv, a subsequent make will not update the default environment. - If CONFIG_DEFAULT_ENVIRONMENT_PATH changes, the default environment also will not be regenerated. This patch fixes this by introducing a cmd_env which has the content of $(ENV_FILES) in the command so that the if_changed mechanism recognizes a change when $(ENV_FILE) changes. This also results in a nice " ENV " string in the build process. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
