* fdt: Update functions which write to an FDT to return -ENOSPCSimon Glass2014-06-11-12/+23
| | | | | | | | | | When writing values into an FDT it is possible that there will be insufficient space. If the caller gets a useful error then it can potentially deal with the situation. Adjust these functions to return -ENOSPC when the FDT is full. Signed-off-by: Simon Glass <sjg@chromium.org>
* fdt: Add DEV_TREE_BIN option to specify a device tree binary fileSimon Glass2014-06-11-3/+19
| | | | | | | | | | | | | | In some cases, an externally-built device tree binary is required to be attached to U-Boot. An example is when using image signing, since in that case the .dtb file must include the public keys. Add a DEV_TREE_BIN option to the Makefile, and update the documentation. Usage is something like: make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb Signed-off-by: Simon Glass <sjg@chromium.org>

* Check that u-boot.bin size looks correctSimon Glass2014-06-11-1/+13
| | | | | | | | | | | | Check that the image size matches the size we get from u-boot.bin. If it doesn't, that generally means that some extra sections are being added to u-boot.bin, meaning that it is not possible to access data appended to the U-Boot binary. This is used for device tree, so needs to work. This problem was introduced by commit b02bfc4. By adding a test we can prevent a reccurence. Signed-off-by: Simon Glass <sjg@chromium.org>

* tools: include u-boot version of sha256.hJeroen Hofstee2014-06-11-0/+1
| | | | | | | | | | | When building tools the u-boot specific sha256.h is required, but the host version of sha256.h is used when present. This leads to build errors on FreeBSD which does have a system sha256.h include. Like libfdt_env.h explicitly include u-boot's sha256.h. cc: Simon Glass <sjg@chromium.org> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl> Acked-by: Simon Glass <sjg@chromium.org>
* Makefile: fix clang warnings due to clang supportJeroen Hofstee2014-06-11-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building u-boot tools with clang as a host compiler e.g. on FreeBSD with `gmake HOSTCC=clang CONFIG_USE_PRIVATE_LIBGCC=y tools` leads to many warnings [1] for every compiler invocation since commit 598e2d33. Part of mentioned commit imports linux patches: - kbuild: LLVMLinux: Adapt warnings for compilation with clang - kbuild: LLVMLinux: Add Kbuild support for building kernel with Clang No version of clang supports the gcc fno-delete-null-pointer-checks though, but it is only passed to clang. Gcc does not have the clang specific Qunused-arguments for the target. Furthermore several warnings are disabled which aren't encountered in u-boot. Since such a build has worked for quite some time and works after removing these changes, just remove the clang specific handling to restore normal building with clang as hostcc. [1] Actual warnings ------------------- GEN include/autoconf.mk.dep arm-freebsd-gcc: unrecognized option '-Qunused-arguments' HOSTCC scripts/basic/fixdep clang: warning: argument unused during compilation: '-fno-delete-null-pointer-checks' cc: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This mirrors the conventions used in other SPI drivers (kirkwood, davinci, atmel, et al) where the din/dout buffer can be NULL when the received/transmitted data isn't important. This reduces the need for allocating additional buffers when write-only/read-only functionality is needed. In the din == NULL case, the received data is simply not stored. In the dout == NULL case, zeroes are transmitted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ci_ep_alloc_request() avoids allocating multiple request objects for ep0 by keeping a record of the first req allocated for ep0, and always returning that instead of allocating a new req. However, if this req is ever freed, the record of the previous allocation is not cleared, so ci_ep_alloc_request() will keep returning this stale pointer. Fix ci_ep_free_request() to clear the record of the previous allocation. Signed-off-by: Stephen Warren <swarren@nvidia.com>

This appears to be valid in many cases; both USB enumeration and Mass Storage work OK with this restriction. However, DFU uses ep0 to transfer data in both directions. This renders the assumption invalid; when sending data from device to host, the Data Stage is an IN transaction, and the Status Stage is an OUT transaction. Enhance handle_setup() to deduce the correct direction for the USB transactions based on Setup transaction data. ep0's request object only needs to be automatically re-queued when the Data Stage completes, in order to implement the Status Stage. Once the Status Stage transaction is complete, there is no need to re-queue the USB request, so don't do that. Don't sent USB request completion callbacks for Status Stage transactions. These were queued by ci_udc itself, and only serve to confuse the USB function code. For example, f_dfu attempts to interpret the 0-length data buffers for Status Stage transactions as DFU packets. These buffers contain stale data from the previous transaction. This causes f_dfu to complain about a sequence number mismatch. Signed-off-by: Stephen Warren <swarren@nvidia.com>
| * | usb: ci_udc: pre-allocate ep0 reqStephen Warren2014-06-01-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocate ep0's USB request object when the UDC driver is probed. This solves a couple of issues in the current code: a) A request object always exists for ep0. Prior to this patch, if setup transactions arrived in an unexpected order, handle_setup() would need to reply to a setup transaction before any ep0 usb_req was created. This issue was introduced in commit 2813006fecda "usb: ci_udc: allow multiple buffer allocs per ep." b) handle_ep_complete no longer /has/ to queue the ep0 request again after every single request completion. This is currently required, since handle_setup() assumes it can find some request object in ep0's request queue. This patch doesn't actually stop handle_ep_complete() from always requeueing the request, but the next patch will. Signed-off-by: Stephen Warren <swarren@nvidia.com>
| * | usb: ci_udc: use a single descriptor for ep0Stephen Warren2014-06-01-11/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | ci_udc currently points ep->desc at separate descriptors for IN and OUT. These descriptors only differ in the ep address IN/OUT field. Modify the code to use a single descriptor, and change that descriptor's ep address to indicate IN/OUT as required. This removes some data duplication.

| * | usb: ci_udc: detect queued requests on ep0Stephen Warren2014-06-01-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flipping of ep0 between IN and OUT relies on ci_ep_queue() consuming the current IN/OUT setting immediately. If this is deferred to a later point when the req is pulled out of ci_req->queue, then the IN/OUT setting may have been changed since the req was queued, and state will get out of sync. This condition doesn't occur today, but could if bugs were introduced later, and this error-check will save a lot of debugging time. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we wait the correct specification-mandated time at the end of usb_hub_power_on(), I suspect that CONFIG_USB_HUB_MIN_POWER_ON_DELAY has no purpose. For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY, so this change is safe. For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY iff pgood_delay was at least 200ms. I'm not sure if this is the case or not, hence I've CC'd relevant people to test this change.

However, these two operations must occur in series rather than in parallel. First, the power supply ramps up to the level required to power the USB device, and then the device may take a certain amount of time to connect (assert D+/D- pullups). Related, the maximum time that a device has to assert pullups is 1s not 100ms. This is explained in "Connect Timing ECN.pdf", itself part of usb_20_042814.zip from www.usb.org.
