* board_enables: reconstruct tableLuc Verhaegen2009-04-201-421/+43
| | | | | | | | | | | | | This patch restores the pciid based board matching table. It makes this table readable and hackable again, and the only disadvantage is that the right margin is way beyond the rather dogmatic 80. All 0x0000 pci ids have been string replaced by 0 to more easily spot missing ids, and extra comments have been added to explain how the various entries are used.

* This patch adds "high coreboot table support" to coreboot version 2Stefan Reinauer2009-03-172-8/+29
| | | | | | | | | | | | | | | | | | | Some bootloaders seem to overwrite memory starting at 0x600, thus destroying the coreboot table integrity, rendering the table useless. By moving the table to the high tables area (if it's activated), this problem is fixed. In order to move the table, a 40 bytes mini coreboot table with a single sub table is placed at 0x500/0x530 that points to the real coreboot table. This is comparable to the ACPI RSDT or the MP floating table. This patch also adds "table forward" support to flashrom and nvramtool. Corresponding to flashrom svn r421 and coreboot v2 svn r4012.

* Reduce use of volatile variablesCarl-Daniel Hailfinger2009-03-061-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the conversion of flash chip accesses to helper functions, I spotted assignments to volatile variables which were neither placed inside the mmapped ROM area nor were they counters. Due to the use of accessor functions, volatile usage can be reduced significantly because the accessor functions take care of actually performing the reads/writes correctly. The following semantic patch spotted them (linebreak in python string for readability reasons, please remove before usage): @r exists@ expression b; typedef uint8_t; volatile uint8_t a; position p1; @@ a@p1 = readb(b); @script:python@ p1 << r.p1; a << r.a; b << r.b; @@ print "* file: %s line %s has assignment to unnecessarily volatile variable: %s = readb(%s);" % (p1[0].file, p1[0].line, a, b) Result was: HANDLING: sst28sf040.c * file: sst28sf040.c line 44 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 43 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 42 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 41 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 40 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 39 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 38 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 58 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 57 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 56 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 55 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 54 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 53 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 52 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); The following semantic patch uses the spatch builtin match printing functionality by prepending a "*" to the line with the pattern: @@ expression b; typedef uint8_t; volatile uint8_t a; @@ * a = readb(b); Result is: HANDLING: sst28sf040.c diff = - tmp = readb(bios + 0x1823); - tmp = readb(bios + 0x1820); - tmp = readb(bios + 0x1822); - tmp = readb(bios + 0x0418); - tmp = readb(bios + 0x041B); - tmp = readb(bios + 0x0419); - tmp = readb(bios + 0x040A); } static __inline__ void unprotect_28sf040(volatile uint8_t *bios) @@ -49,13 +42,6 @@ static __inline__ void unprotect_28sf040 /* ask compiler not to optimize this */ volatile uint8_t tmp; - tmp = readb(bios + 0x1823); - tmp = readb(bios + 0x1820); - tmp = readb(bios + 0x1822); - tmp = readb(bios + 0x0418); - tmp = readb(bios + 0x041B); - tmp = readb(bios + 0x0419); - tmp = readb(bios + 0x041A); } static __inline__ int erase_sector_28sf040(volatile uint8_t *bios, It's arguably a bit easier to read if you get used to the leading "-" for matching lines.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-0517-342/+372
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now we perform direct pointer manipulation without any abstraction to read from and write to memory mapped flash chips. That makes it impossible to drive any flasher which does not mmap the whole chip. Using helper functions readb() and writeb() allows a driver for external flash programmers like Paraflasher to replace readb and writeb with calls to its own chip access routines. This patch has the additional advantage of removing lots of unnecessary casts to volatile uint8_t * and now-superfluous parentheses which caused poor readability. I used the semantic patcher Coccinelle to create this patch. The semantic patch follows: @@ expression a; typedef uint8_t; volatile uint8_t *b; @@ - *(b) = (a); + writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + readb(b) @@ type T; T b; @@ ( readb | writeb ) (..., - (T) - (b) + b ) In contrast to a sed script, the semantic patch performs type checking before converting anything.

| | | | | | | | | | | | | Elan SC520 requries us to deal with flash chip base addresses at locations other than top of 4GB.
