* Remove sys/boot/arm/at91 and ixp425Warner Losh2017-10-2565-9321/+0
| | | | | | | | | | | | | Remove at91 bootloader. It only worked on AT91RM9200, and only specific boards that were all EOLd 10 years ago. Remove ixp425. It doesn't build anymore and is for boards that were EOLd 8 years ago. Sponsored by: Netflix Notes: svn path=/head/; revision=324982

* Revert r321969Enji Cooper2017-08-033-14/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My change had good intentions, but the implementation was incorrect: - printf was returning the number of characters in the format string plus the NUL, but failed in two regards implementation wise: -- the pathological case, printf(""), wasn't being handled properly since the pointer is always incremented, so the value returned would be off-by-one. -- printf(3) reports the number of characters printed post-conversion via vfprintf, etc. - putchar(3) should return the character printed or EOF, not the number of characters output to the screen. My goal in making the change (again) was to increase parity, but as bde pointed out these are freestanding functions, so they don't have to conform to libc/POSIX. I argued that the functions should be named differently since the implementation is different enough to warrant it and to allow boot2 code to be usable when linked against sys/boot and libstand and other libraries in base. I have no interest in pushing this change forward more though, as the original concern I had behind the change with zfsboottest was resolved in r321849 and r321852. The next person that updates the toolchain gets to deal with the inconsistency if it's flagged by a newer compiler. MFC after: 1 month Reported by: ed, markj Notes: svn path=/head/; revision=321991

* Enable at91 systems to boot from high capacity SD cards.Ian Lepore2014-07-263-142/+278
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also fixes a few minor violations of the SD protocol, such as running the bus at high speed during the card identification sequence. The sdcard_init() routine now probes for SDHC cards so that later read requests can make needed adjustments between block and byte offsets based on card type. There is a new MCI_readblocks() function that takes block number and block count parameters instead of byte-offset values. Using this routine, boot loader code can load a kernel from any location on an SDHC or standard SD. The old MCI_read() interface remains unchanged so that existing customized boot loader code will still keep working without changes. Using this routine, boot loaders can load a kernel from anywhere in the first 4GB of an SDHC card (or of course any location on a standard SD card). A new sdcard_use4wire() routine allows boot loaders to request 4-bit transfers; it should be called after sdcard_init(). The sdcard_init() routine no longer assumes the hardware is 4-wire capable and by default sets things up for 1-bit transfers. (4-wire mode is unreliable on at91rm9200, works on later SoCs.)

| | | | | | | | | | | | | | | | | | | | | | | | - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

| | | | | | | | | | | | | | | | | | | CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards) it is 1024 (or 2048 for 4GB). This value doesn't work for the block read commands (which really want 512). Hardcode 512 for those. This may break really old MMC cards that don't have a 512 block size (I've never seen one: make my day and send me one :-), but since the MMC side of the house is currently broken, it should only have the effect that 2GB (and non-conforming 4GB) SD cards will work. My 'non-conforming' 4GB SD card also works now too. The non-conforming 4GB SD cards were sold for a while before the SD association was worried they would be (a) incompatible (different FAT flavor on them) and (b) confusing for the new SDHC standard and cracked down on suppliers' bogus use of the SD trademark...
