It is better to print "Reserved for root" than
"Reserved pool size", because it is more obvious for users
what this means.

The CFI information read from AT49BV6416 lists the erase regions in the
wrong order, causing problems when trying to erase or update the first
or last 64KiB block.
Work around this by inverting the "top boot" flag, which will
effectively reverse the order of the erase regions.
This chip is obsolete, but it's used in some existing designs.

This patch adds TopBottom detection for most Macronix chips with CFI V1.0.
The main purpose of this patch is to add detection of the MX29LV400C B
used on the LaCie Ethernet Disk mini V2 NAS.
It detects the following parts correctly:-
MX28F640C3B T
MX29LV002C B
MX29LV002NC B
MX29LV004C T
MX29LV400C T/B
MX29LV800C T/B
MX29LV160C T/B
MX29SL800C T/B
MX29SL802C T/B
It detects the following uniform part as bottom but it should work
correctly:-
MX29LV040C
For T parts it causes the erase block table to be reversed correctly.
For other parts it avoids the bogus "Assuming top" message.
It does not detect the following correctly:-
MX28F640C3B B
MX29LV002C T
MX29LV002NC T
MX29LV004C B
MX29SL400C T/B
MX29SL402C T/B
If desired I could supply a more complicated patch to handle these as
well.
Only the MX29LV400C B has been physically tested; others were checked
against their data sheets.

This was causing a BUG() on NOR-ECC (Sibley) flash, where we start

This patch (as1149) fixes an obscure problem in OHCI polling. In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:
The interrupt handler is the only place where RHSC status
gets turned back off;
The interrupt handler won't turn RHSC status off because it
doesn't turn off status flags if the corresponding interrupt
isn't enabled;
RHSC interrupts will never get enabled because
ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
status is on!
As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.
Of course, this is a bug. The proper thing to do is to turn off RHSC
status just before reading the actual port status values. That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on. Possibly both, but that
won't hurt anything.
We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses. (This re-read has to be done anyway, to post the earlier
write.) If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.
