* fs: fix standard zero, full devicesSascha Hauer2012-07-041-3/+3
| | | | | | | | | | | | | | | | The standard devices are currently broken since they have the size ~0. As now files use loff_t as file size which is a signed type the read implementation gets confused and now returns -1. The current implementation also has the (somewhat theorical) problem that we do not have real streaming devices, so /dev/zero went out of zeroes after reading 4GB (or now LLONG_MAX). This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new file size flag FILE_SIZE_STREAM which makes it possible to create real stream devices instead.

| * resource: store 'end' instead of 'size' in struct resourceSascha Hauer2012-07-013-7/+4
| | | | | | | | | | | | | | | | | | | | Storing the size instead of the resource end in struct resource was a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | booting: more flexible Linux bootargs generationSascha Hauer2012-05-142-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use the environment variable 'bootargs' to get the Linux bootargs. This patch allows for a more flexible bootargs generation using global variables. With it the Linux bootargs are concatenated from multiple variables. This allows to replace parts of the bootargs string without having to reconstruct it completely. With this bootargs can be constructed like: global linux.bootargs.base="console=ttyS0,115200" global linux.bootargs.ip="ip=dhcp" global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)" This will then automatically be combined into a kernel bootargs string during boot. If the 'linux.bootargs.' variables are all empty the old standard 'bootargs' way will be used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | add 'global' commandSascha Hauer2012-05-143-0/+70
| | | | | | | | | | | | | | | | | | | | | | This implements global shell variable support. This is done by registering a new device named 'global', so global variables are just plain device parameters. Global variables are useful for storing the global state in the environment. Currently we do this by sourcing scripts instead of executing them which is quite limiting. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
