ANANDA KRISHNAN" Date: Wed, 27 Jul 2005 11:43:48 -0700 Subject: [PATCH] jsm: use dynamic major number allocation The jsm driver uses a static number of 253. The major number 253 is a reserved for "LOCAL/EXPERIMENTAL USE" by both char and block devices. So take advantage of the dynamic allocation of major number by the kernel. Signed-off-by: V.

This card is a little controversial since it is the subject of a PCI vendor/device ID clash. (See http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have for now just used the hex ID 0x950a. The divisor was part calculated part iterated, so may not be exactly correct (but works for me at all settings between 300 - 115300 bps).

Change it to use the on-board DPRAM instead. The current code relies on the "bootmem_page" allocated by m8xx_cpm_reset(), which must be killed. This is done in v2.4 but has never been forward ported to v2.6.
