* env_mmc: support env partition setup in runtimeDmitry Lifshitz2014-08-01-12/+23
| | | | | | | | | | | | Add callback with __weak annotation to allow setup of environment partition number in runtime from a board file. Propagate mmc_switch_part() return value into init_mmc_for_env() instead of -1 in case of failure.

* | Add a flag indicating when the serial console is readySimon Glass2014-07-23-2/+2
| | | | | | | | | | | | | | | | | | | | For sandbox we have a fallback console which is used very early in U-Boot, before serial drivers are available. Rather than try to guess when to switch to the real console, add a flag so we can be sure. This makes sure that sandbox can always output a panic() message, for example, and avoids silent failure (which is very annoying in sandbox). Signed-off-by: Simon Glass <sjg@chromium.org>
* | console: Remove vprintf() optimisation for sandboxSimon Glass2014-07-23-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | If the console is not present, we try to reduce overhead by stopping any output in vprintf(), before it gets to putc(). This is of dubious merit in general, but in the case of sandbox it is incorrect since we have a fallback console which reports errors very early in U-Boot. If this is defeated U-Boot can hang or exit with no indication of what is wrong. Remove the optimisation for sandbox. Signed-off-by: Simon Glass <sjg@chromium.org>
* | stdio: Provide functions to add/remove devices using stdio_devSimon Glass2014-07-23-8/+24
| | | | | | | | | | | | | | | | | | The current functions for adding and removing devices require a device name. This is not convenient for driver model, which wants to store a pointer to the relevant device. Add new functions which provide this feature and adjust the old ones to call these.

* | dm: Allow drivers to be marked 'before relocation'Simon Glass2014-07-23-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver model currently only operates after relocation is complete. In this state U-Boot typically has a small amount of memory available. In adding support for driver model prior to relocation we must try to use as little memory as possible. In addition, on some machines the memory has not be inited and/or the CPU is not running at full speed or the data cache is off. These can reduce execution performance, so the less initialisation that is done before relocation the better. An immediately-obvious improvement is to only initialise drivers which are actually going to be used before relocation. On many boards the only such driver is a serial UART, so this provides a very large potential benefit. Allow drivers to mark themselves as 'pre-reloc' which means that they will be initialised prior to relocation. This can be done either with a driver flag or with a 'dm,pre-reloc' device tree property. To support this, the various dm scanning function now take a 'pre_reloc_only' parameter which indicates that only drivers marked pre-reloc should be bound.

* | stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-25/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

* | Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>

* | Add option -r to env import to allow import of text files with CRLF as line ↵Alexander Holler2014-07-22-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | endings When this option is enabled, CRLF is treated like LF when importing environments from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored. Drawback of enabling this option is that (maybe exported) variables which have a trailing CR in their content will get imported without that CR. But this drawback is very unlikely and the big advantage of letting Windows user create a *working* uEnv.txt too is likely more welcome. Signed-off-by: Alexander Holler <holler@ahsoftware.de>

|/ | | | | | | | | | | | | | | | | | | | | | Use get_device_and_partition() is better since: 1. It will call the device initialize function internally. So we can remove the mmc intialization code to save many lines. 2. It is used by fatls/fatload/fatwrite. So saveenv & load env should use it too. 3. It can parse the "D:P", "D", "D:", "D:auto" string to get correct device and partition information by run-time. Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string: FAT_ENV_DEVICE_AND_PART. For at91sam9m10g45ek, it is "0". That means use device 0 and if: a)device 0 has no partition table, use the whole device as a FAT file system. b)device 0 has partittion table, use the partition #1.

* sandbox: restore ability to access host fs through standard commandsStephen Warren2014-06-23-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | Commit 95fac6ab4589 "sandbox: Use os functions to read host device tree" removed the ability for get_device_and_partition() to handle the "host" device type, and redirect accesses to it to the host filesystem. This broke some unit tests that use this feature. So, revert that change. The code added back by this patch is slightly different to pacify checkpatch. However, we're then left with "host" being both: - A pseudo device that accesses the hosts real filesystem. - An emulated block device, which accesses "sectors" inside a file stored on the host. In order to resolve this discrepancy, rename the pseudo device from host to hostfs, and adjust the unit-tests for this change. The "help sb" output is modified to reflect this rename, and state where the host and hostfs devices should be used.

* Add an I/O tracing featureSimon Glass2014-06-20-0/+244
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging drivers it is useful to see what I/O accesses were done and in what order. Even if the individual accesses are of little interest it can be useful to verify that the access pattern is consistent each time an operation is performed. In this case a checksum can be used to characterise the operation of a driver. The checksum can be compared across different runs of the operation to verify that the driver is working properly. In particular, when performing major refactoring of the driver, where the access pattern should not change, the checksum provides assurance that the refactoring work has not broken the driver. Add an I/O tracing feature and associated commands to provide this facility. It works by sneaking into the io.h heder for an architecture and redirecting I/O accesses through its tracing mechanism. For now no commands are provided to examine the trace buffer. The format is fairly simple, so 'md' is a reasonable substitute. Note: The checksum feature is only useful for I/O regions where the contents do not change outside of software control. Where this is not suitable you can fall back to manually comparing the addresses. It might be useful to enhance tracing to only checksum the accesses and not the data read/written.
