* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-583/+1
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* common: Convert the U-Boot commands to LG-arraysMarek Vasut2012-10-22-42/+50
| | | | | | | | | | | | | | | | | | This patch converts the old method of creating a list of command onto the new LG-arrays code. The old u_boot_cmd section is converted to new u_boot_list_cmd subsection and LG-array macros used as needed. Minor adjustments had to be made to the common code to work with the LG-array macros, mostly the fixup_cmdtable() calls are now passed the ll_entry_start and ll_entry_count instead of linker-generated symbols. The command.c had to be adjusted as well so it would use the newly introduced LG-array API instead of directly using linker-generated symbols.

* common: Implement support for linker-generated arraysMarek Vasut2012-10-22-0/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for linker-generated array. These arrays are a generalization of the U-Boot command declaration approach. Basically, the idea is to generate an array, where elements of the array are statically initialized at compile time and each element is declared separatelly at different place. Such array is assembled together into continuous piece of memory by linker and a pointer to it's first entry can then be retrieved via accessor. The actual implementation relies on placing any variable that is to represent an element of LG-array into particular subsection of the .u_boot_list linker section . The subsection is determined by user options. Once compiled, it is possible to dump all symbols placed in .u_boot_list section and the subsections in which they should be and generate appropriate bounds for each requested subsection of the .u_boot_list section. Each such subsection thus contains __start and __end entries at the begining and end respecitively. This allows for simple run-time traversing of the array, since the symbols are properly defined.

* common: Add symbol handling for generic lists into MakefileMarek Vasut2012-10-22-25/+152
| | | | | | | | | | | | | | | | | | | | | | | This patch adds essential components for generation of the contents of the linker section that is used by the linker-generated array. All of the contents is held in a separate file, u-boot.lst, which is generated at runtime just before U-Boot is linked. The purpose of this code is to especially generate the appropriate boundary symbols around each subsection in the section carrying the linker-generated arrays. Obviously, the interim linker code for actual placement of the variables into the section is generated too. The generated file, u-boot.lst, is included into u-boot.lds via the linker INCLUDE directive in u-boot.lds . Adjustments are made in the Makefile and spl/Makefile so that the u-boot.lds and u-boot-spl.lds depend on their respective .lst files.

* powerpc/usb: fix bug of CPU hang when missing USB PHY clockShengzhou Liu2012-10-22-6/+16
| | | | | | | | | | | | | when missing USB PHY clock, u-boot will hang during USB initialization when issuing "usb start". We should check USBGP[PHY_CLK_VALID] bit to avoid CPU hanging in this case. Due to controller issue of PHY_CLK_VALID in ULPI mode, we set USB_EN before checking PHY_CLK_VALID, otherwise PHY_CLK_VALID doesn't work.

* usb: fallback safely when a configuration descriptor is too largeVincent Palatin2012-10-22-3/+9
| | | | | | | | | | | | | | | When a USB configuration descriptor was larger than our USB buffer (512 bytes), we were skipping the full descriptor reading but then we were still parsing and using it, triggering memory corruptions. Now in that case, it just skips this device enumeration and displays the appropriate message to the user, so he can fix the buffer if he wants. This bug was triggered by some UVC webcams which have very large configuration descriptors (e.g. a couple of kB) describing all their supported video encodings.

* usb: Support the CONFIG_SYS_64BIT_LBA optionGabe Black2012-10-22-10/+14
| | | | | | | | | | | | | | | | usb_storage wouldn't compile when the CONFIG_SYS_64BIT_LBA option is turned on because the used fixed size data types in their exported functions when they should have used lbaint_t for the block count parameter. That meant that when the sizes happened to be the same, when using a 28 bit LBA, the driver would build, but when it wasn't, a 48 bit LBA, things broke. This change adjusts the signatures to use the right type and makes small adjustments in the affected functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | empty On x86, the i8042 keyboard controller driver frequently waits for the keyboard input buffer to be empty to make sure the controller has had a chance to process the data it was given. The way the delay loop was structured, if the controller hadn't cleared the corresponding status bit immediately, it would wait 1ms before checking again. If the keyboard responded quickly but not instantly, the driver would still wait a full 1ms when perhaps 1us would have been sufficient. Because udelay is a busy wait anyway, this change decreases the delay between checks to 1us. Also, this change gets rid of a hardcoded 250ms delay. On Stumpy, this saves 100-150ms during boot.

Make sure to initialize all fields in the partition descriptor in that case. The value chosen for name is just some arbitrary descriptive string. The value chosen for info matches the check at the end of get_device_and_partition(). However, it's probably not that important; it's not obvious that the value is really used.
