* Fix number base handling of "load" commandWolfgang Denk2013-10-07-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As documented, almost all U-Boot commands expect numbers to be entered in hexadecimal input format. (Exception: for historical reasons, the "sleep" command takes its argument in decimal input format.) This rule was broken for the "load" command; for details please see especially commits 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" and 3f83c87 "fs: fix number base behaviour change in fatload/ext*load". In the result, the load command would always require an explicit "0x" prefix for regular (i. e. base 16 formatted) input. Change this to use the standard notation of base 16 input format. While strictly speaking this is a change of the user interface, we hope that it will not cause trouble. Stephen Warren comments (see [1]): I suppose you can change the behaviour if you want; anyone writing "0x..." for their values presumably won't be affected, and if people really do assume all values in U-Boot are in hex, presumably nobody currently relies upon using non-prefixed values with the generic load command, since it doesn't work like that right now.

* fs: fat: don't call disk_write with zero sector numWu, Josh2013-09-06-3/+5
| | | | | | | | | | | | | | In the set_cluster() function, it will convert the buffer size to sector numbers. Then call disk_write() to write by sector. For remaining buffer, the size is less than a sector, call disk_write() again to write them in one sector. But if the total buffer size is less then one sector, the original code will call disk_write() with zero sector number. It is unnecessary. So this patch fix this. Now it will not call disk_write() if total buffer size is less than one sector. Signed-off-by: Josh Wu <josh.wu@atmel.com>

* Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy2013-07-15-60/+80
| | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>

Officially supported u-boot toolchains (eldk-5.[12].x) generate calls to __aeabi_uldivmod(), which is niether defined in the toolchain libs nor u-boot source tree.

* fs: fix number base behaviour change in fatload/ext*loadStephen Warren2012-11-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" unified the implementation of fatload and ext*load with the new command fsload. However, this altered the interpretation of command-line numbers from always being base-16, to requiring a "0x" prefix for base-16 numbers. Enhance do_fsload() to allow commands to specify which base to use. Use base 0, thus requiring a "0x" prefix for the new fsload command. This feels much cleaner than assuming base 16. Use base 16 for the pre-existing fatload and ext*load to prevent a change in behaviour. Use base 16 exclusively for the loadaddr environment variable, since that variable is interpreted in multiple places, so we don't want the behaviour to change. Update command help text to make it clear where numbers are assumed to be hex, and where an explicit "0x" prefix is required.
