[U-Boot] driving a serial peripheral in u-boot
by Dexdyne Postmaster 12 Aug '09

12 Aug '09

Our AVR32 board has a GSM modem attached.. I'd like to send an SMS at power-on, though if we successfully boot Linux it will do more sophisticated stuff. If we get the SMS, then nothing further we know the boot failed. Is there an example anywhere of u-boot talking to a device on a serial port ( which is not the console ) I can use as an example?

[U-Boot] Where is the GPR30 register in PowerPC arch as GOT pointer documented?
by Gao Ya'nan 12 Aug '09

I find nothing about this in (E)ABI specification(perhaps some old), so, where is it? Thanks.

Is this going to be used by any other NAND controllers? If it's not a particularly common thing, perhaps the DaVinci NAND controller driver should just override the read_page method. Even if it's shared, the alternative read_page should probably be provided in library form for the controller driver to use if desired. We should move most of the so-called generic NAND stuff in that direction; currently it bloats u-boot even on hardware that doesn't need it. > This patch has been accepted by Andrew Morton and can be found at > > http://userweb.kernel.org/~akpm/mmotm/broken-out/mtd-nand-add-new-ecc-mode-… That's a testing tree -- it's not actually "accepted" if it's not in the mtd tree (or Linus's). > + case NAND_ECC_HW_OOB_FIRST: > + /* Similar to NAND_ECC_HW, but a separate read_page handle */ > + if (!chip->ecc.calculate || !chip->ecc.correct || > + !chip->ecc.hwctl) { > + printk(KERN_WARNING "No ECC functions supplied, " > + "Hardware ECC not possible\n"); > + BUG(); > + } > + if (!chip->ecc.read_page) > + chip->ecc.read_page = nand_read_page_hwecc_oob_first; Would anyone ever use this with read_page non-NULL? It seems like its whole point is to overide that. -Scott

[U-Boot] [PATCH v4 2/2] zlib: add watchdog reset call
by Giuseppe CONDORELLI 11 Aug '09

11 Aug '09

This patch adds watchdog reset call to allow its invokation during decompression phase. This control was present on old zlib version and here it is backported for those relevant routines. This patch is sent as a zlib separate one beacuse it was not tested due to specific board lack. zlib patches will be unified just in one when this will be validated through tests.
