* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* Remove AmigaOneG3SE boardWolfgang Denk2010-06-23-8/+1
| | | | | | | | | | The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.

* FIX: watchdog timeout, while waiting for inputJens Scharsig2010-04-10-0/+3

* cmd history: Match history buffer size to console bufferJohn Schmoller2010-03-21-1/+1
| | | | | | | | Match history buffer size to console buffer size. History buffer size was hard coded to 256, artificially limiting the command buffer size. The history buffer now tracks CONFIG_SYS_CBSIZE. Signed-off-by: John Schmoller <jschmoller@xes-inc.com>
* console: Fix console buffer overrunJohn Schmoller2010-03-21-2/+2
| | | | | | | | | When CONFIG_SYS_CBSIZE equals MAX_CMDBUF_SIZE, a command string of maximum length will overwrite part of the history buffer, causing the board to die. Expand the console_buffer and hist_lines buffer by one character each to hold the missing NULL char. Signed-off-by: John Schmoller <jschmoller@xes-inc.com>
* Move CONFIG_UPDATE_TFTP code after CONFIG_PREBOOTWolfgang Denk2010-03-11-4/+4
| | | | | | | | | | | | The auto-update feature (CONFIG_UPDATE_TFTP) requires that the env variable serverip be set for the TFTP access. If DHCP is to be used to get the serverip env variable, this doesn't work as DHCP happens after the auto-update attempt has run. A solution is to run DHCP in PREBOOT, but even this is too late. To solve this, we move update_tftp() below the PREBOOT stuff. Signed-off-by: Wolfgang Denk <wd@denx.de>
* readline(): Add ability to modify a string bufferPeter Tyser2009-10-27-0/+10
| | | | | | | | | | | | If the 'buf' parameter is a non-0-length string, its contents will be edited. Previously, the initial contents of 'buf' were ignored and the user entered its contents from scratch. This change is necessary to support the upcoming "editenv" command but could also be used for future commands which require a user to modify an existing string.

* Check for NULL prompt in readline_into_buffer()Peter Tyser2009-10-27-1/+2
| | | | | | | | | | | | | Previously, passing readline() or readline_into_buffer() a NULL 'prompt' parameter would result in puts() printing garbage when CONFIG_CMDLINE_EDITING was enabled. Note that no board currently triggers this bug. Enabling CONFIG_CMDLINE_EDITING on some boards (eg bab7xx) would result in the bug appearing. This change is only intended to prevent someone from running into this issue in the future. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Remove inline qualifier from show_boot_progress()Emil Medve2009-05-15-1/+1
| | | | | | | | | | | The 'inline' is conflicting with the semantic of 'weak' attribute and with the way the show_boot_progress() function is used. Also gcc 4.4 is complaining about it: main.c:51: error: inline function 'show_boot_progress' cannot be declared weak Signed-off-by: Emil Medve <Emilian.Medve@Freescale.com>

| | | | | | | | | | | Support bootdelay=0 in abortboot for the CONFIG_AUTOBOOT_KEYED case similar to the CONFIG_ZERO_BOOTDELAY_CHECK support for the !CONFIG_AUTOBOOT_KEYED case. Do this by reversing the loop so we do at least one iteration before checking for timeout. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* hush: add showvar command for hush shell.Heiko Schocher2008-10-18-0/+4
| | | | | | | | | | | | | | | | | | | | This new command shows the local variables defined in the hush shell: => help showvar showvar - print values of all hushshell variables showvar name ... - print value of hushshell variable 'name' Also make the set_local_var() and unset_local_var () no longer static, so it is possible to define local hush shell variables at boot time. If CONFIG_HUSH_INIT_VAR is defined, u-boot calls hush_init_var (), where boardspecific code can define local hush shell variables at boottime. Signed-off-by: Heiko Schocher <hs@denx.de>
* Automatic software update from TFTP serverBartlomiej Sieka2008-10-18-0/+7
| | | | | | | | | | | The auto-update feature allows to automatically download software updates from a TFTP server and store them in Flash memory during boot.

* Fix printf errors.Andrew Klossner2008-07-09-1/+1
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Fix readline_into_buffer() with CONFIG_CMDLINE_EDITING before relocatingJames Yang2008-05-09-10/+23
| | | | | | | | | | | When CONFIG_CMDLINE_EDITING is enabled, readline_into_buffer() doesn't work before relocating to RAM because command history is written into a global array that is not writable before relocation. This patch defers to the no-editing and no-history code in readline_into_buffer() if it is called before relocation.
