Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs. The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

- Fix some typos in mmc_acquire_bus() and mmc_send_csd(). - Fix some math errors in mmc_decode_csd_sd(). - Fix incorrect arguments to mmc_send_app_op_cond() in mmc_go_discovery(). - Add reporting of CSD for debug purposes. - Add detection (and skipping) of password-locked cards. - Add setting of block length on card if necessary.

o Fixes: - When switching to 4-bit operation, send a SET_CLR_CARD_DETECT command to disconnect the card-detect pull-up resistor from the DAT3 line before sending the SET_BUS_WIDTH command. - Add the missing "reserved" zero entry to the mantissa table used to decode various CSD fields. This was causing SD cards to report that they could run at 30 MHz instead of the maximum 25 MHz mandated in the spec. o Enhancements: - At the MMC layer, format various info from the CID into a string that uniquely identifies the card instance (manufacturer number, serial number, product name and revision, etc). Export it as an instance variable. - At the MMCSD layer, display the formatted card ID string, and also report the clock speed of the hardware (not the card's max speed), and the number of bits and number of blocks per transfer. It comes out like this now: mmcsd0: 968MB at mmc0 22.5MHz/4bit/128-block o Use DEVMETHOD_END. o Use NULL instead of 0 for pointers. PR: 156496 Submitted by: Ian Lepore

1. Both mmc_read_ivar() and sdhci_read_ivar() use the expression '*(int *)result = val' to assign to result which is uintptr_t *. This does not work on big-endian 64 bit systems. 2. The media_size ivar is declared as 'off_t' which does not fit into uintptr_t in 32bit systems, change this to long. Submitted by: kanthms at netlogicmicro com (initial version)

It was just a cosmetic issue, because that number is only reported in logs. Reported by: Michael Butler on current@
