| * env_mmc: allow environment to be in an eMMC partitionStephen Warren2012-09-071-8/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | eMMC devices may have hardware-level partitions: 2 boot partitions, up to 4 general partitions, plus the user area. This change introduces optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which partition the environment should be stored in: 0=user, 1=boot0, 2=boot1, 4..7=general0..3. This allows the environment to be kept out of the user area, which simplifies the management of OS-/user-level (MBR/GPT) partitions within the user area.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change hashtable so that a callback function will decide whether a variable can be overwritten, and possibly apply the changes. So add a new field to struct hsearch_data: o "apply" callback function to check whether a variable can be overwritten, and possibly immediately apply the changes; when NULL, no check is performed. And a new argument to himport_r(): o "do_apply": whether to call the apply callback function NOTE: This patch does not change the current behavior.

The current code ends up allocating one copy of env_t for each byte in its size, which quite possibly ends up overflowing RAM. This fixes a bug in commit 3801a15 "env_nand: align NAND buffers".

* | cmd_sf: add size checking to spi flash commandsGerlando Falauto2012-04-031-0/+14
|/ | | | | | | | | | | SPI flash operations inadvertently stretching beyond the flash size will result in a wraparound. This may be particularly dangerous when burning u-boot, because the flash contents will be corrupted rendering the board unusable, without any warning being issued. So add a consistency checking so not to overflow past the flash size. Signed-off-by: Gerlando Falauto <gerlando.falauto@keymile.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* usb_storage: fix ehci driver max transfer sizeStefan Herbrechtsmeier2012-07-181-17/+20
| | | | | | | | | | | | | | | | The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage: Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in usb_storage as it wrongly assumes that every transfer can use 4096 bytes per qt_buffer. This is wrong if the start address of the data is not page aligned to 4096 bytes and leads to 'EHCI timed out on TD' messages because of 'out of buffer pointers' in ehci_td_buffer function. The bug appears during load of a fragmented file and read from or write to an unaligned memory address.
