* pci: introduce CONFIG_PCI_INDIRECT_BRIDGE optionGabor Juhos2013-06-07-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pci_indirect.c file is always compiled when CONFIG_PCI is defined although the indirect PCI bridge support is not needed by every board. Introduce a new CONFIG_PCI_INDIRECT_BRIDGE config option and only compile indirect PCI bridge support if this options is enabled. Also add the new option into the configuration files of the boards which needs that. Compile tested for powerpc, x86, arm and nds32. MAKEALL results: powerpc: --------------------- SUMMARY ---------------------------- Boards compiled: 641 Boards with warnings but no errors: 2 ( ELPPC MPC8323ERDB ) ---------------------------------------------------------- Note: the warnings for ELPPC and MPC8323ERDB are present even without the actual patch. x86: --------------------- SUMMARY ---------------------------- Boards compiled: 1 ---------------------------------------------------------- arm: --------------------- SUMMARY ---------------------------- Boards compiled: 311 ---------------------------------------------------------- nds32: --------------------- SUMMARY ---------------------------- Boards compiled: 3 ---------------------------------------------------------- Cc: Tom Rini <trini@ti.com> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com> Signed-off-by: Gabor Juhos <juhosg@openwrt.org>

* tpm: Reorganize the I2C TPM driverTom Wai-Hong Tam2013-06-03-0/+13
| | | | | | | | | | | | | | | | | | | This patch does a similar code reogranzation from http://patchwork.ozlabs.org/patch/132179/ which is based on an old version of code (fdt support and bus selection still not in). It merges this tidy-up on top of the recent code. It does not make any logical change. tpm.c implements the interface defined in tpm.h based on underlying LPC or I2C TPM driver. tpm.c and the underlying driver communicate throught tpm_private.h. Note: Merging the LPC driver with tpm.c is left to future patches.

| * | ARM: OMAP5: Fix warm reset with USB cable connectedLokesh Vutla2013-05-10-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Warm reset on OMAP5 freezes when USB cable is connected. Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Downloaded from http://slre.sourceforge.net/ and adapted for U-Boot environment. Used to implement regex operations on environment variables. Code size is ~ 3.5 KiB on PPC. To enable this code, define the CONFIG_REGEX option in your board config file. Note: There are more recent versions of the SLRE library available at http://slre.googlecode.com ; unfortunately, the new code has a heavily reorked API which makes it less usable for our purposes: - the return code is strings, which are more difficult to process - we don't get any information any more which sub-string of the data was matched by the given regex - it is much more cumbersome to work with arbitrary expressions, where for example the number of substrings for capturing are not known at compile time Also, there does not seem to be any real changes or improvements of the functionality. Because of this, we deliberately stick with the older code. Note 2: the test code (built when SLRE_TEST is defined) was modified to allow for more extensive testing; now we can test the regexp matching on all lines on a text file (instead of the whole data in the file as a single block).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.

If it is defined in the board file, then consider 16-bit NAND bus-width, otherwise assume 8-bit NAND is used.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "mtest" command is of little practical use (if any), and experience has shown that a large number of board configurations define useless or even dangerous start and end addresses. If not even the board maintainers are able to figure out which memory range can be reliably tested, how can we expect such from the end users? As this problem comes up repeatedly, we rather do not enable this command by default, so only people who know what they are doing will be confronted with it. As this changes the user interface, we allow for a grace period before this change takes effect. For now, we make "mtest" configurable through the CONFIG_CMD_MEMTEST variable, which is defined in include/config_cmd_default.h; we also add an entry to doc/feature-removal-schedule.txt which announces the removal of this default setting in two releases from now, i. e. with v2013.07.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sandbox doesn't actually provide U-Boot access to the machine's physical memory. Instead it provides a RAM buffer of configurable size, and all memory accesses are within that buffer. Sandbox memory starts at 0 and is CONFIG_DRAM_SIZE bytes in size. Allowing access outside this buffer might produce unpredictable results in the event of an error, and would expose the host machine's memory architecture to the sandbox U-Boot. Most U-Boot functions assume that they can just access memory at given address. For sandbox this is not true. Add a map_sysmem() call which converts a U-Boot address to a system address. In most cases this is a NOP, but for sandbox it returns a pointer to that memory inside the RAM buffer. To get a U-Boot feature to work correctly within sandbox, you should call map_sysmem() to get a pointer to the address, and then use that address for any U-Boot memory accesses.

| * powerpc/mpc83xx: add support for new SPLScott Wood2012-12-19-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | This adds arch support for PPC mpc83xx to boot "minimal" (4K) SPLs using the new infrastructure. Existing nand_spl targets are updated to deal with the name change from nand_init.c to spl_minimal.c (as in theory this isn't limited to NAND anymore).
